This would be an extension of the CSV extension. Instead of dumping CSVs directly to the screen, you can first declare the raw CSV data as a block tag (either embed it as you do now or reference a file/url) and then have other block tags after it referencing that data. For example...

Display the data (just as we do now)
Plot the data (line, bar, ...)
Download the data
etc...

One option is gnuplot.

Fail if 'set terminal ...' is anything other than SVG
Fail if 'set output ...'
Every other part of gnuplot should be fine.

Added support for basic SVG gnuplots, but keep this open because maybe it's worth integrating CSV with gnuplots or provide another more robust charting/graphing library (for things other than plots)

No longer required. Have support for programming languages -- it's easy to call matplotlib.
