[Haskell-cafe] ANN: diagrams 0.4

[Rustom Mody]

Thanks.  This is attractive.
I remember (vaguely) a 'live page' ie where one could enter (into the
browser) changes to the diagrams code and see the results immediately.
Is that page there? (Or am I mixing up with something else?)

How does diagrams compare with graphviz?  If this is an inappropriate
(type-wrong?) question thats ok :-)  Its just that when I last looked at
graphviz I found the documentation somewhat impenetrable -- like much else
in Hackage -- lots of types, no examples.
