A class with Edward Tufte
Me and couple of my colleagues from the office had been to Arlington,VA for a day's class with Edward Tufte. It was a fun trip and great experience. Coincidently I had started reading Tufte's "Visual Display of Quantitative Information".
I liked most of the class but there were parts which I definitely did not agree with. May be I am not mature enough to grasp the points. Some of the highlights of the class were.
* While presenting quantitative information, data is more important than design. Show data, hide design.
* Present data such that it enables the user's cognitive process instead of hindering it.
* Show comparisons, show causality.
* Show multivariate data, that is data showing relationships between two or more variables.
* Integrate words and diagrams. Tufte illustrated this by showing how Galileo displayed the rings around the planet Saturn integrated along with the words in his text.
* Present all of the information available, do not cherry pick data that makes you look good. In case you don't have information that seems interesting, try harder and work towards getting better numbers.
* In case the numbers that you are presenting are small in quantity (like 40 - 80), present them directly (may be using a table) rather than using graphs.
* Refer to distinguished newspaper and tech journals to see how they present data using tables etc. May be you will be able to get ideas from those. Remember "Smart guys imitate, while geniuses copy"
* The consumers of your information aren't stupid people. They are smart to deal with numbers and graphs. Don't most of the people read the tables the in the sports section or the stock section of the newspaper?
* Also when presenting information, it important to include a title, measurement scales, cite the sources, name the authors as well as any other relevant information in text form.
Also an important lesson that I learned from the trip was that I have some great colleagues that I work with. The overall experience of the trip proved that we are a great team together.
