We are looking for a nice javascript-based library for a web charting application we have been asked to do. The charts will be accessible and should actually be nice to interact with via mobile devices (iOS, Android, and the like). The user will be able to drill-down into some datasets, so the snappier (both processing graphics and loading data) and the more interactive, the better.
Nowadays, there are countless options out there, and many aspects to look at. Based on my research, I have put together the following list. Apologies beforehand for any mistake, it is not intended to be 100% complete or accurate.. but I think that still useful:

What is your opinion? Do you have any experiences in such kind of application? Maybe some candidate I am missing?
We are narrowing down the choice, but I am still not sure as for what choice is the best bet. Some questions that pop-up in my mind:
- Different ways of rendering the chart (SVG/VML versus HTML 5 canvas). Which one is more suited to browsers in mobile devices? Which one is more suited to user interaction?
- Making it look good. Which libraries allow to easily tweak appearance? Is CSS really powerful for this?
