Hi all,

I've been playing for a weeks now with the canvas class of OpenLayers.
If the SVG class draw multiple elements (one for each GML feature), the
canvas class draw only one file.

In this two example the charts are draw by a php libary :
> http://geotribu.net/node/50 (Artichow)
> http://blog.thematicmapping.org/2008/04/openlayers-and-google-chart-mashup.html
> (google chart)

Instead of using a php library I would like to draw them with one of the
javascript library like :

> http://vis.stanford.edu/protovis/
> http://solutoire.com/plotr/
> http://code.google.com/p/flotr/

Do you know how for each feature i could draw a canvas graph?

Thanks for your help

Regards

Arnaud
