Serge,

Thanks for finding out about this.  It looks like we are free to write our own implementation.

As I said in my previous post, it looks fairly simple to draw the chart.

Are you planning to write a view?  I can make a start on it if you don't have time.

Nick, best discuss this on devel list.
I would expect also some design is needed for such a view.
