We use goffice for graphing.  It's the graphing engine from gnumeric, so
it fundamentally supports everything that gnumeric can do.

The gnucash reports, however, only support basic scatter, box and pie
charts.

It's relatively straightforward to support new types, however.  See the
handle_{piechart,barchart,scatter} in
src/gnome-utils/gnc-html-graph-gog.c to get an idea of how much is
involved.  That's the side that gets a callback from GtkHtml for an
<object> tag in the report-generated html that contains a particular
type of chart data.  Note that there's a corresponding chunk of code on
the scheme report side to emit the appropriately-formatted <object>
block in the HTML, of course.
