Data visualization is becoming a catch-all concept with little analytic usefulness. The infographic plague we have to endure is not helping. It doesn’t have to be that way. Stephen Few wrote recently about the distinction between data visualization (“the goal that data be visualized in a way that leads to understanding”) and data art (“visualizations … Read more
Stephen Few left a comment in my post “Is Data Visualization Useful? You’ll Have to Prove it“. We all have much to learn with Steve, so instead of leaving the discussion buried in an old post, I thought it would be interesting to make it more visible. Please read the comment then come here and … Read more
From time to time, Seth Godin comes to visit our little field of information visualization, and I’m pleased to note that he is learning… Today’s post, “How to make graphs that work” is remarkably better than “The three laws of great graphs” or “How to make a PowerPoint chart”. Today he warns us against Excel … Read more
Hans Rosling was here in Lisbon today, for one of his remarkable presentations. It seems that almost no one in the room new about his TED talks and, of course, everyone loved his charts. He gave his presentation in Portuguese, so some extra points there too… If you just return to planet Earth and don’t … Read more
1. Tufte, the Father of Eye-Candy Charts Tufte’s The Visual Display of Quantitative Information, published in 1983, is probably the most influential book in the history of data visualization, and it is likely to remain so for some more time. In his book, Tufte outlines for the first time a consistent theory of how a … Read more
Seth’s blog is always interesting, and usually I agree with him and learn something. However, when he discusses charts and graphs he’s often a very light purple cow. This week he confirms that. Godin’s The three laws of great graphs tells us that, when using graphs in presentations, we should follow these simple principles: “one … Read more
Do you prefer the full report: Or the executive summary? For Tufte’s fans, Minard’s map plays a central role in Tufte’s iconography, and the way he praises it (“best statistical graphic ever”) is quoted endlessly (974 results in Google as of today, to be precise). Tufte discussed The Map in his first book (The … Read more
An alarming level of the “what-would-Tufte-say” syndrome can be found in this post and some of its comments discussing a New York Times’s infographic. This syndrome has some recognizable features like the extensive use of “chart junk”, “lie factor” or other terms and expressions coined by Tufte that reveal a somewhat misunderstanding or abusive usage … Read more
Well, I must say I am a bit disappointed with the September issue of Stephen Few’s Visual Business Intelligence Newsletter. It discusses an important but much neglected topic, visualizing change through animation. Few’s paper was written for SAS Institute, and uses JMP, a statistical analysis product from them. From the screenshots, I wouldn’t say I … Read more
