Borderline off-topic:

What are the best open-source charting libraries available right now (in terms of looks)? D3 or not, although I'll prefer D3, as it would be easier to extend.

I'm looking for something as pretty as Highcharts, to use in open-source apps.

flot (http://www.flotcharts.org/) has been a loyal friend for years.

Any comments on flot vs flotr2?

I'm trying to choose which to use for a project, and I can't find much reason to prefer one over the other.
