Add charts to the statics page #2632
Description
Could be powered by the dc.js library (which is build on top of d3.js and crossfilter)
The awesome thing about that library is that it allows for cross-filtering - all charts are interactive, and setting filters in one chart affects all others.
Additionally, whatever charts are implemented in the stats page, it would be good to also have them available in the query results (i.e, show the counts when data is grouped by some field)
