Renaud Drousies signale une petite merveille javascript : Plotkit, de liquidx. Cette bibliothèque JavaScript permet de créer des graphiques en ligne, directement. Au lieu de produire les images sur le site PHP, il est possible d'envoyer directement les données dans le javascript, et de laisser le navigateur faire le rendu. Liquidx produit des courbes, des camenberts ou des barres. La bibliothèque est capable de produire des fichiers SVG ou HTML canva, et est compatible avec Safari 2, Firefox 1.5, Internet Explorer 6 et Opera 9.

Some time ago I was looking for a charting framework for Prototype and I couldn’t find it, just because there’s none. So that’s where it all started. I came across PlotKit, a well written piece of javascript that enables developers to use Canvas or SVG elements for rendering bar, line and pie charts. The only thing was that PlotKit needed the Mochikit library to work. So I took some parts of PlotKit and wrote some parts myself. The result is a lightweight charting framework (12kb!) named Plotr. It’s released under the BSD license.

Semiophore Explorer et Miner supportent désormais l'export de graphes au format GraphML.
A Java-based toolkit for building interactive information visualization applications.
GraphML is a comprehensive and easy-to-use file format for graphs. It consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application-specific data. Its main features include support of * directed, undirected, and mixed graphs, * hypergraphs, * hierarchical graphs, * graphical representations, * references to external data, * application-specific attribute data, and * light-weight parsers.
