I've updated my Graphviz extension hacks. It now includes two new entry points that cause an image to be text flowed left or right without using tables. See the Annotated examples at the link below. (The text flow example is the last one on that page.)

---------------- previous message ----------------- I wanted to use other layout engines besides dot(1), so I hacked Graphviz.php to allow a Unix-style interpreter specification for the other rendering engines in Graphviz. This is backwards compatible (since it is a legal dot comment) and avoids coming up with new syntax.

The interpreter spec must immediately follow the opening tag: "<graphviz>#!/sw/bin/neato" for example. I explicitly check for allowed rendering engines to avoid script injection security issues.

Enjoy!

PS: It would be nice to have "out of band" communications with extensions, like <graphviz engine="neato">. It could simply bundle up everything it finds in the tag into an associative array. This would be very useful (for example) in text-wrapping, since so many extensions seem to generate images. (<graphviz style="float:right">, for example)
