No I hadn't heard of that project but I'll try and contact the author
-  it would be good to collaborate. He's using gRaphael for chart
plotting and downloading JSON data from the server.
I had already thought that it might be nice to download the initial
data as raw RRD files and then update the charts using smaller JSON
data requests - or perhaps stream the data directly to the clients by
adapting Collectd network plugin protocol to web sockets or some other
Comet system.

JSON and RRD datasources can share the same API as could Flot and
gRaphael chart plotters. I'm thinking about copying parts of the
Google Visualisation API:

Thanks for the Visage link.
