For anything more than say 50-100 nodes or edges, Graph Navigation becomes a design issue IMNO. So this question.

How difficult or easy would it be to replace the typical .dot etc generated PNG, JPEG or GIF formats with a more dynamic widget? I am of course thinking of Dynagraph http://www.graphviz.org/Documentation/EGKNW03.pdf - but also, in general, a way by which the graph can be made more interactive (hover on node shows/or/highlites only the subgraph, instead of all nodes, zoom in- and out- of a graph).

The Graphviz Filter Formats contains a renderer for SVG that can embed the ZGRViewer Applet. Are you asking about something like that?

Yes, it can work.

To embed ZGRViewer:

* Download the ZGRViewer Appler and copy the zvtm.jar and zgrviewer.jar files to the graphviz_filter module location, ensuring that their filenames are as written here
* Enable the Graphviz Filter Formats module
* In your Graphviz script, specify the arguments @formats = svg and @zgrviewer = TRUE

Title: Navigation or Applet/Flash/Flex stuff? » Dynamic Graph Navigation: ZGRViewer integration
Version: 6.x-1.x-dev » 6.x-1.6
Category: feature » support

Fantastic!
This would really need to be mentioned in the documentation!

However, the url linking does not seem to work.
Is this hopeless, meaning we have to chose between static png image with links or dynamic navigation without linking capabilities?

However, the url linking does not seem to work.

Do you mean URL linking does not work from within the applet? Can you find out if ZGRViewer has known issues with this feature, outside of Graphviz Filter?

I just found that one needs to double click to activate the hyperlink... as the simple click as a neat navigation pointer.
Great add-on, really bring life to Graphviz and Drupal.

http://sourceforge.net/projects/zvtm/files/zgrviewer/ seems obsolete
It redirects to http://sourceforge.net/projects/zvtm/

Is this compatible too? The files look different

No, the link is working for me. The latest ZGR Viewer applet (0.8.2) is from 2009. Note that Sourceforge has been experiencing flakiness for about a month now.

OK, I have checked again too.
Thanks

Any way to get the viewer full screen?
(I could extend the window size by altering the applet call in code)
