nice! I think eventually it'd be sweet to have more generic svg outlines, etc. but for now I think screenshots are okay / way better than nothing.

LGTM after rebase?

SO COOL

IMO we should make these widgets configurable. For instance, sometimes a given widget is not useful for certain distribution of data. In that case users can still see the widgets available in the drop down. Can we make these widgets configurable so that it can be customized by admin. - Just a thought ;)

@sid88in , yeah we could eventually have global settings (withelist/blacklist), and same at the datasource level perhaps.
