I need to generate some PDF reports (1000s). Part of the report is a set of
bar charts (the results of a questionnaire). Each question has the same 5
answers (v.bad, bad, ok ,good, v.good) and the chart is the % distribution
of the answers.

My plan is to create a HTML version, using "some graph drawing"* (saving a
copy of the HTML to disk), creating a PDF version using html2pdf (saving a
copy to disk and emailing to the recipient).

I think html2pdf can handle this. But I have not had much success finding
something to draw my graphs. Any (free) simple libraries out there I could
be pointed towards?
