Author of the Comparison of Charting modules, and co-maintainer of these charting related modules, for which the major goal is to implement Chart 2.0:

• Chart (+/- 26K sites), the most installed (popular?) Drupal module for charting.
• Charts (+/- 10K sites), 2nd most installed Drupal charting module, and generally perceived as the most appropriate alternative of the Chart module.
• Visualization (+/- 3K sites), yet another charting module, somehow similar to Charts.
• Quant and Visualize, 2 hidden gems for charting in Drupal.

New project owner of these modules:

• Visitors, which also includes **charting** features but without depending on any of the typical charting modules.
• CSV Chart, which depends on Chart, to add charts in a node (no need for the dangerous PHP code filter ...). Still D5-only today, but about to be upgraded to D6/D7.

Also a co-maintainer of the Forena module, for which most of its community documentation was created. And a major upgrade of the documentation that comes with it was contributed, about how to configure, use and extend it.
