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.
Last week I got faced with two very interesting libraries.
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.
