Classic Visualization Papers

7 Classic Foundational Vis Papers You Might not Want to Publicly Confess you Don’t Know by Enrico Bertini.

From the post:

Even if I am definitely not a veteran of infovis research (far from it) I started reading my first papers around the year 2000 and since then I’ve never stopped. One thing I noticed is that some papers recur over and over and they really are (at least in part) the foundation of information visualization. Here is a list of those that:

  1. come from the very early days of infovis
  2. are foundational
  3. are cited over and over
  4. I like a lot

Of course this doesn’t mean these are the only ones you should read if you want to dig into this matter. Some other papers are foundational as well. For sure a side effect of the maturation of this field is that some newer papers are more solid and deep and I had to refrain myself to not include them in the list. But this is a collection of classics. A list of papers you just cannot avoid to know unless you want to risk a bad impression at VisWeek (ok ok it’s a joke … but there’s a pinch of truth in it). A retrospective. Definitely a must read. Call me nostalgic.

Take the time to read Enrico’s post and the papers he cites. Whatever your experience with visualization, you will be enriched by the experience.

I first saw this in “the sixth issue of DashingD3js.com’s Weekly Newsletter” but I can’t give you a link to it that is not tied to my subscription. ?? Nor is there an archive page for the newsletter posts. Until those issues are corrected, see: http://www.dashingd3js.com/.

Popcorn infographics

Popcorn infographics by Aleksey Nozdryn-Plotnicki.

From the post:

On my way to Crete recently, I was flipping through the in-flight magazine when I stumbled upon this treat. This full-page piece was about Claire Cock-Starkey’s upcoming (at the time) book, Seeing the Bigger Picture.

You have to see the graphics for most of the post to work but thought it worth calling to your attention.

The book appears to be one of those that claim: “…no one has ever done it this way before.” You don’t have to read very carefully to discover there is a good reason why that is true.

Or to quote Alexksey when he cites a review of the book:

“Bought this for my 14 yr old – absolutely loves it and showed friends who were also suitably impressed. Thank you”

Seeing the Bigger Picture by Claire Cock-Starkey. Publisher: London : Michael O’Mara, 2012. I could not find any professional reviews as of November 19, 2012.

Can information be beautiful when information doesn’t exist?

Can information be beautiful when information doesn’t exist? by Kaiser Fung.

From the post:

Reader Steve S. sent in this article that displays nominations for the “Information is Beautiful” award (link). I see “beauty” in many of these charts but no “information”. Several of these charts have appeared on our blog before.

Kaiser comments on a number of the graphics that I pointed to in: Information is Beautiful Awards – The Results Are In!

Kaiser is far better qualified than I am to comment on the suitability of the graphics chosen.

I am less confident in his ability to judge the information contained by a graphic.

The information content of a graphic, like its semantics, doesn’t exist separate and apart from the reader/viewer.

If you think it does, do you have an example of information or semantics in the absence of a reader/viewer?

Do read Kaiser’s comments to get a different take on some of the graphics.

A chart that stops the story-telling impetus

A chart that stops the story-telling impetus

From the post:

We all like to tell stories. One device that has produced a lot of stories, and provoked much imagination is the dual-axis plot showing two time series. Is there a correlation or is there not? Unfortunately, most of these stories are false.

The post proceeds to illustrate that the relationship it depicts isn’t present in another presentation of the data. (Using “…home sales and median home price in Claremont over the last six years…” as a data set.

I don’t disagree that a different depiction of the same data is, well, different, but that was the point of the exercise. Yes?

That is to say that I would not make a chart of data that contradicted some point I was trying to make in an argument. Or at least that I understood was contradicting some point I was trying to make.

My personal rule is that when someone shows me a chart, statistics, test results, analysis of any sort, they are trying to persuade me that one or more facts are the case. What else would they be trying to do? (There is annoy me but let’s set that case to one side.)

I think library students and others need to be aware that vendors use charts and other means of persuasion because they are marketing a product. Not in bad faith because they may really believe their product will suit your needs as well as their need for a sale. A win-win situation.

What you need to do is push back with your understanding of the “facts,” with your own charts or interpretation of their charts.

Just as a tip, have your needs and your users’ needs depicted in colorful charts for sales meetings. So you can put a big red X on any feature you need that the vendor doesn’t offer. That is the card/chart you need to have on top of the stack at all times.

6 Reasons Why Infographics and Data Visualization Works

6 Reasons Why Infographics and Data Visualization Works by Matthew Fields.

Here are the reasons (see the post for reasons and the infographic):

  1. Short Attention Spans
  2. Information Overload
  3. Easy to Understand
  4. Reading Retention
  5. More Engaging
  6. People Love Sharing Infographics

What I find interesting is the effective use of text before you get to the infographic.

And there are some points I would add to the list:

  • No Thinking Required
  • Reinforces Prejudices
  • Shallow Understanding
  • Infographic Replaces Data

The last one, Infographic Replaces Data, is the most dangerous.

The debate shifts from what the data may or may not show, upon additional analysis, to what the infographic may or may not show.

Do you see the shift? If you allow me (or anyone else) to create an infographic, we have implicitly defined the boundaries of discussion. We are no longer talking about the “data” (although we may use that terminology) but about an infographic that has replaced the data.

In other words, if you don’t agree with the infographic, you have already lost the debate. Because we are not debating the “data,” but rather my infographic. Which I fashioned because it supports my opinion, obviously.

Thinking infographics as brainwashed data would not be too far off the mark.

Some infographics are worse than others, in terms of shifting the basis for discussion. I will round up some good examples for a future post.

The war on infographics

The war on infographics

Kaiser Fung writes:

Megan McArdle (The Atlantic) is starting a war on the infographics plague. (Here, infographics means infographics posters.) Excellent debunking, and absorbing reading.

It’s a long post. Her overriding complaint is that designers of these posters do not verify their data. The “information” shown on these charts is frequently inaccurate, and the interpretation is sloppy.

In the Trifecta checkup framework, this data deficiency breaks the link between the intent of the graphic and the (inappropriate) data being displayed. (Most infographics posters also fail to find the right chart type for the data being displayed.)

There are two reasons to read this post and then to follow up with Megan’s:

First, it may (no guarantees) sharpen your skills at detecting infographics that are misleading, fraudulent or simply wrong.

Second, if you want to learn how to make effective and misleading, fraudulent or simply wrong infographics, Megan’s article is a starting place with examples.
