A Periodic Table of Visualization Methods – [Visualization]

In their 2007 research paper Towards A Periodic Table of Visualization Methods for Management Ralph Lengler & Martin J. Eppler created a periodic table of 100 visualization methods. The paper abstract describes the research as “effort of defining and compiling existing visualization methods in order to develop a systematic overview based on the logic, look, and use of the periodic table of elements.”

They describe a Visualization method as:

a systematic, rule-based, external, permanent, and graphic representation that depicts information in a way that is conducive to acquiring insights, developing an elaborate understanding, or communicating experiences.

Visual-literacy.org have an interactive visualization of the table with a pop-up example of each visualization method upon mouse-over. It provides a fantastic framework for understanding and describing the multitude of visualization methods and styles available.
A Periodic Table of Visualization Methods

From the research paper:

The periodic table is constructed along two dimensions: Periods and groups. Of the five dimensions we deemed most relevant for a pragmatic classification of visualization methods, we found the dimension of complexity of visualization most fitting for “periods” and application area most fitting for “groups”.

As we classified the visualization methods along those two dimensions we also tried to organize them in a similar way. That means as you move down a column, you will find similar methods for similar purposes but getting more and more complex. This is an ordinal meas- ure within a group, meaning you will find in one period different amounts of complexity. This is for pragmatic reasons as we didn’t want to leave any empty spaces in the table. For example, a line chart is a more complex visualization method than a spectrogram (a single line having two extreme poles). On the other hand a tensor diagram is more complex than a spectrogram

The chart has the application area dimension (“groups”) into the following categories and distinguished them by background color:

  • Data Visualization includes standard quantitative formats such as Pie Charts, Area Charts or Line Graphs. They are visual representations of quantitative data in schematic form (either with or without axes), they are all-purpose, mainly used for getting an overview of data.
  • Information Visualization, such as semantic networks or treemaps, is defined as the use of interactive visual representations of data to amplify cognition. This means that the data is transformed into an image; it is mapped to screen space.
  • Concept Visualization, like a concept map or a Gantt chart; these are methods to elaborate (mostly) qualitative concepts, ideas, plans, and analyses through the help of rule-guided mapping procedures.
  • Metaphor Visualization, like metro map or story template are effective and simple templates to convey complex insights. Visual Metaphors fulfill a dual function, first they position information graphically to organize and structure it.
  • Strategy Visualization, like a Strategy Canvas or technology roadmap is defined “as the systematic use of complementary visual representations to improve the analysis, development, formulation, communication, and implementation of strategies in organizations.”
  • Compound Visualization consists of several of the aforementioned formats. They can be complex knowledge maps that contain diagrammatic and metaphoric elements, conceptual cartoons with quantitative charts, or wall sized info murals. (Note: The Periodic table above is a Compound Visualization)

The periodic table also puts the three other dimensions on top of the method symbol and used the following pictorial representations:

1. Task and Interaction: Depending on the task, visualization can emphasize certain aspects of the data.

  • Overview [ ☼ ], most visualization methods are good in providing an overview.
  • Detail AND Overview [ ۞ ], those methods adhere in one way or another to Shneiderman’s visualization mantra i.e. Overview first, zoom and filter, then details on demand.
  • Detail [ ¤ ], those methods are good in providing (additional) insights from single bits of data.

2. Cognitive Processes: Visualization methods can help the user to articulate implicit knowledge (as in a visual metaphor) and to stimulate new thinking (like with a mindmap).

  • Convergent thinking [ >< ] is a mode of critical thinking in which a person attempts to reduce complexity through analysis and synthesis.
  • Divergent thinking [ <> ] is a mode of thinking in which a person generates many unique, creative responses to a question or problem.

3. Represented Information: Structure or Process as a mechanism for representing data

  • Structure [in black], such as hierarchies or networks
  • Process [in blue], either stepwise cyclical in time and/or continuous sequential.

The paper concludes with the underlying rational for structuring an explanation of the hundreds of visualization methods in a style similar to the periodic table:

With our table we do not mean to reveal the organizing principle of visualization methods, but we want to highlight the fact that there might not be only one appropriate visualization method for a given requirement. Rather, there is the potential of employing a combination of different methods to enhance the achieved results.

Our efforts in structuring the vast domain of visualization methods cannot be seen as a close adaptation of the peri- odic table of chemical elements. It is rather a functional, metaphoric homage to it. The choice of methods included as well as the order criteria cannot be considered exhaus- tive. Nevertheless, it does provide an overview over more than hundred useful visualization methods of great variety and by organizing them assists researchers and practitio- ners alike in choosing adequate visualization methods for their needs.

Критика таблицы: Visualization is not Periodic, Period!

by Евгений Волков -

Visualization is not Periodic, Period!


Periodic Table of Visualization Methods

Of all the sins committed against visualization on the Internet, the Periodic Table of Visualization Methodsstands out as the most egregious. Its collection of actual visualization methods, structural diagrams, and feel-good business bullshit does not fit a structure that was devised to understand the world – and that is actually a very effective visualization in itself.

Visualization Methods

A good part of the left half of the diagram is comprised of actual visualization methods. There are line charts, bar charts, parallel coordinates, etc. Of course, there’s already a taste of the things to come in the “Continuum” and the “Scenario Matrix” example for Cartesian coordinates. And even though the Information Visualization category is defined as being based on data, it contains flow charts, entity relationship models, etc., which are part of the next category.

Structural Diagrams

These are diagrams that are not based on data in the sense that they visualize a dataset. These are modeling tools, and they are useful, but they are not visualizations. Flow charts, entity relationship models, etc. provide a means of depicting and reason about structures, like the control flow in a program or the table layout in a database.

Most of these are under the Information Visualizationcategory, while the remaining categories like Concept VisualizationStrategy Visualization, etc. fall under the next heading.

Feel-Good Business Bullshit

Argument Slide, Force Field Diagram

You need to fill the time at those seminars with something. When you’re not teaching your clients to juggle, ride a unicycle, or fire-walk, you talk about theArgument Slide or the Force Field Diagram. It helps pass the time, and everybody enjoys sharing information in such an informal setting. And it’s exactly the kind of stuff that keeps the Dilbert guy in business drawing his terrible cartoons. This is not visualization.

The Structure

Adding insult to injury, the structure they have abused is actually a remarkable visualization in itself. The Periodic Table of Elements was developed by Dmitri Mendeleev after discovering patterns in how different elements behaved depending on the number of valence electrons (electrons in the outermost layer around the atom) and the number of layers. The simple ordering in the table nicely groups the elements into different kinds of metals, non-metals, noble gases, etc.

The table provides a kind of visualization of the underlying data (the number of electrons), revealing its periodic structure. It organizes the information about elements in a way that makes the relationships between elements obvious; much like the white and black keys on a piano keyboard.

Other Idiotic Periodic Tables

Visualization is not the only thing the periodic table can be misapplied to. There is a Periodic Table of Typefaces, a Periodic Table of Texting (a t-shirt that’s apparently no longer sold), a Periodic Table of Beer, a Periodic Table of Awesomeness, etc. Of course, none of these depict structures that are actually periodic. Camdon Wilde, who designed the typefaces table, freely admits that:

Unfortunately, the typefaces could not be sorted exactly numerically on the table while at the same time keeping them in groups of families and classes. It had to be one or the other. Of course it COULD have been done but I would have had to seriously sacrifice aesthetics of the overall design (i.e. it wouldn’t have come out looking AT ALL like a traditional periodic table.)

There is something about this structure that is vaguely familiar, has an air of science, and the fact that people like structure (just look at all those lists out there on the Internet) that just draws people in and compels them to email all the people they know about this abomination.

When you get that next email pointing you to this awesome resource, don’t forward it. Only you can stop this nonsense.

10 thoughts on “Visualization is not Periodic, Period!”

  1. Why did you cross out “Idiotic”? I have disliked these pseudo-scientific displays since the first one I ever ssaw. There’s no periodicity, no order by row or column. Just some doofus pigeonholing items almost at random in a familiar grid.

  2. Anonymoussays:

    Dilbert is terrible? C’mon!

  3. stephenfewsays:


    It’s nice to read an opinion of “The Periodic Table of Information Visualization” that is consistent with mine from another person working in the field. I wrote about the absurdity of this display back on January 8th, 2007and even used it as an example of the kind of display that gives infovis a bad name in my capstone presentation at InfoVis 2007. Until now, I have only read one other negative opinion besides yours, which was written by Juan Dürsteler in May, 2007. This display is so embarrassingly ineffective, it’s surprising that when it was getting so much positive attention when it was first published that others working in our field didn’t raise their voices to say that it did not represent what information visualization has to offer. Was this because academics are loathe to criticize the work of other academics? Isn’t academia the proper place for such critique?


  4. To be honest, the visualization is as bad as several of the visualization it references. Academic rigor would call for a more decent classification – which definitely would not fit into the periodic system framework.

    InfoVis has a certain artistic freedom which makes is often hard to classify. The “only” important dimension which might be left for any kind of visualization is the efficiency a visualization has in coding resp. decoding information.


  5. Robert Kosarasays:

    But that’s the thing: what makes them so attractive? There must be some psychological effect behind this.

  6. Robert Kosarasays:

    I remember reading your posting, I just didn’t think of it when writing this. You’re much more systematic about pointing out the flaws in this design.

    But regarding criticism in academia: that would be a good idea. But in many cases, that is done in private, and usually without telling the person whose work is being discussed – unless it’s a review, in which case the reviewer/critic is anonymous. We don’t have a culture of criticism, and many people are in fact very adverse (critical?) of it. That’s why I keep pushing the idea: if it was what everybody was doing, there would be no point in doing that.

    We need a lot more critical writing, so people don’t just see the endless, mindless reblogging, but a spectrum of thoughts and opinion. See also: A Better Vis Web Community

  7. Anonymoussays:

    You raise some good “qualified” points about the errors, omissions, and logic flaws of this particular representation. But at the same time I wonder if this is the best way for a community of infovis practitioners to “criticize” the works of others. Reminds me a bit of walking through a museum and saying “that painting sucks” – can you do better? Let us see your attempt to make better of a valid goal to provide a useful visualization of visualization methods. I’m sure you could count on the community to provide useful and constructive inputs to make it better and therefore benefit the effort…the best challenge to nonsense is to make sense…

    I’m not finding any of your own work on this site?

  8. In response to Anonymous asking “where’s yours”, how about Melanie Tory and Torsten Moller’s InfoVis 2004 paper “Rethinking Visualization: A High-Level Taxonomy” (search for it at scholar.google)


  9. Anonsays:

    I stated it in my InfoVis lectures over and over again that there is something severely wrong with that table. Now I have to review VAST 2013 papers citing that very table in an unreflected way. 5 years later – no progress at all it seems…

  10. Speaking as a designer with a science background, it particularly annoys me when someone takes the form of something like the periodic table, which is a brilliant piece of information design conveying a large and complex amount of data about a specific phenomenon, throws out the content and shoehorns in new content which has no reason to be presented in that form. They’ve used it simply because it’s a pre-existing familiar, memorable and structured visual representation – a quick and easy way to jump on a bandwagon. I did once see a version of the periodic table with each element illustrated by a food that contained it. That was meaningful, a periodic table of visualization methods isn’t.

    One example that has particularly incensed me for years is The Great Bear, an artwork by Simon Patterson. Based on the London Underground Tube diagram, the lines have been labelled with categories and the stations with the names of people who fit within those categories. I realise that it’s an artwork designed to question the meaning of categories and labelling, but it still really bugs me that he didn’t make the intersections work properly. For instance, he could have structured it so that the intersection between philosophers and footballers was Albert Camus, but didn’t. Why would you pass up that opportunity? It seems like a good idea let down by poor execution, although maybe part of the point was to irritate pedants like me… (And yes, I start to have a go at redoing it myself: it’s quite difficult!)
