On Tuftefying gnuplot

Marcus Ritt has a nice tutorial on how to make gunplot graphics a little more Tufte.

And Technolope also has some considerations on Tufte and gnuplot.

Latex following Edward Tufte

I was putting some sparklines at an web app I am designing. I am using the "Sparkline PHP Graphing Library" which is a well written PHP library for generating the famous sparklines created by Edward Tufte. So I was wondering which another advice I could pick up from Master Tufte... I went googling arround for Edward Tufte and a bunch of links came up but, the one which most called my attention was a Tufte-inspired LaTeX class for producing handouts, papers, and books. The samples provided by the web site are really well designed.

Javascript, visualization and statistics (Protovis and Jstat)

Last week I got faced with two very interesting libraries.
Protovis
Protovis uses JavaScript and SVG for web-native visualizations. Protovis composes custom views of data with simple marks such as bars and dots.



Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.

jStat jStat is a statistical library written in JavaScript that allows you to perform advanced statistical operations without the need of a dedicated statistical language (i.e. MATLAB or R).

Read Write Web has also an article about other 20 JavaScript Libraries for Data Visualization
