On 11st April Bitergia participated in LGM 2013 presenting the status of VizGrimoireJS, our platform for visualizing metrics.
The hot issue was to use HTML5 Canvas or SVG to create the visualizations. And the key to answer this questions is, are the visualizations going to be edited by other tools? Then, use SVG. If not, the two technologies have pros and cons. Right now, VizGrimoireJS is using the cool Flotr2 library and D3 for some specific graphs, like Treemap. Check it in our live preview.
