Edward Tufte, masterful critic of design and skilled creator of graphs and charts presented to me and 350 or so other people at the Omni New Haven. Unlike reading Tufte’s work, hearing him speak reveals another side – someone who is infuriated with bureaucracy and someone who believes that we are much smarter than we think.

As he does throughout his 4 books on analytical design, he extolled the virtues of artfully rendered charts, graphs, diagrams and lists. He described each of the 9 principles of analytical design, which could be used by anyone to create “workaday” presentations. The principles really are practical, and if applied, more intelligent conversations might be generated. The basics principles are:

Some of these seem obvious, but when you look at most data (i.e. charts and graphs), you’ll see how many of these rules are ignored. Bottom line: most data are presented to support a point, not solve a problem.

Then, came the interesting parts.

Tufte advocates the use of sparklines, a combination of words, a number and a graph that fit in the same space as an average length English word. He suggests that current methods of organizing data by their “accident of production” (i.e. powerpoint, word, excel, email) is wasteful. We’ve become lazy by separating paragraphs from diagrams from charts. We need to make some effort to bring that data together to present a cohesive argument.

Tufte described weaknesses of the web. First, computer monitors operate at 1/10 the resolution of print rendering complex images imprecise. Second, because of their size and resolution, they are unable to present data all in a single visual field, a format with which humans work very well.

Working with Tufte’s principles, and checking presentations and reports against them, could help reduce a lot of information clutter and finally spark the conversations that those presentations and reports were meant to invoke.
