I needed to render some RRD graphs from a Catalyst application. Before, I was using rrdcgi. Not that I couldn't use it together with WrapCGI, but I wanted to write the HTML templates in Template Toolkit (as always), because rrdcgi templating is not all that powerful.

So you get the RRDs perl module on one side, and you get Catalyst on the other, a bit of glue, and there you have it: Catalyst::View::RRDGraph

Just put the graph definition on the stash, and call the view. The view outputs images, so you can use them from an HTML page that you have templated in whatever language you want.

<Img src="[% c.uri_for('controller/that/uses/rrdgraph') %]">

As always, feedback is welcome
