[rrd-users] SVG interaction on RRDs graphs

I have written code for Ganglia (http://ganglia.info) that uses rrdtool 
export to export data of interest then "massages" the data into a proper 
JSON format. I then use Flot (Javascript graphing library) to draw the 
images. You can for instance see how it looks in action if you go here


Find a graph that has an Enlarge button next to it. Click on it. You can 
then hover over the graph value and it will show you current value. This 
is very much work in progress.

There was a patch submitted by Erik Kastner to allow rrdtool to export 
directly to JSON but I have not seen it included.
