Hi there,
The Graphviz plugin is for us the best diagram plugin from DW.
- established popular syntax
- lightweight
- powerful
- can be locally installed (even faster, no internet needed)
However the current version does not implement the URL feature of Graphviz
http://www.graphviz.org/doc/info/attrs.html#d:URL to allow clickable nodes in the resulting graph.
There was an attempt by Enrique M. as documented in the plugin page
https://www.dokuwiki.org/plugin:graphviz but it seems not to work in current versions.
This is such a helpful feature for a documentation diagram (clickable nodes) that the URL feature (dot MAPs) should become part of the plugin. Unfortunately I do not have the skills to do this myself, so I add here the suggestion to the community.
