There is gtkdatabox I hesitate to mention it, because there is a Perl module only for it's earliest version. Google for "Gtk2-Databox" for links to the old versions. The old versions work just fine, and have many features that you request. Possibly, you could pick up on the module, and port the latest gtkdatabox to Perl :-).

If you want to avoid the Canvas type widgets, want to use Perl, and SVG, you might want to go with a DrawingArea. See Drawing with Perl/Gtk2 Special handling is required with a DrawingArea, as opposed to a canvas type widget, because you must deal with the expose event.
