graphs, guppi or Grace?

[Mathew Yeates <mathew fugue jpl nasa gov>]

I considering using Grace instead of guppi (there is now
a  python interface to Grace so I can call it from my
python plugin)

Would there be any advantage to using guppi over Grace? Grace is not
gtk based so I wouldnt have the same look and feel as gnumeric. Also, no
drag and drop support. But Grace is much more mature than guppi and I would
expect it to have alot more features.

Comments?
