Yes. The theme in question can be seen in action here:

http://hgweb.boddie.org.uk/EventAggregator/graph

The problem with the existing graph action is that it takes something of a 
shortcut with the data structures, making them unusable for the templating 
system. Thus, it became necessary to extend the action to supply usable data, 
and at that point I thought that the most acceptable patch was one which 
still provided only one form of graph data, but also provided some conversion 
so that people who had copy-pasted the vertex JavaScript code into their 
theme could still rely on the old data structure format.
