Tweak for interactive SVGs?

[Bill B. <bi...@br...>]

I've been generating some plots that get a bit busy, sometimes it's nice to be
able to toggle what you see.  So I wrote a script to tweak the gnuplot output,
and it generates:
         http://cse.ucdavis.edu/bill/barc.svg

Try clicking on any of key titles like "1-thread add".  Currently it's a short
perl script.  The changes are just things like adding a
onclick=ToggleVisibilty call for each key text entry, adding a id= group for
each line in the graph, and of course the small routine to actually toggle the
visibility.

Any comments on how hard it would be to add to the gnuplot SVG output routine?

How useful?

Would a reasonably written patch to do this be accepted?

It interactive toggle is responsible to around 1400 bytes of that 55kb file.

In any case I find it rather useful, especially when comparing two different
datasets.
