[graphviz-interest] Graphviz/Webdot hosting / installation on a shared server

Hi,

Almost three years ago, I asked the below question on GraphViz/Webdot
hosting. I got a few tentative replies, but nobody had a satisfactory
solution. In the meantime, Google Charts GraphViz came along, which works
okay for small, middle-of-the-road graphs, but lacks many features,
including being able to embed images, use the latest features, generate
seriously-sized maps, etc.

Let me try again. Is there anybody out there who could provide such a
service? Or, less ambitious: is there anybody who knows how to get standard
GraphViz to work on a shared server? Most providers (including mine,
HostGator) do not allow source code to be compiled. Is there perhaps a way
to have the source code listed on

http://graphviz.org/Download..php

compilied outside of my jailed shell-account and ftp the binaries there, so
that I finally, finally, finally would get GraphViz to actually work? It's
such a great tool, and I am so frustrated I can't actually really use it in
my R&D!

Cheers,

Aldo
