Graphing tool for CollectD

We use collectd on our remote servers and need a way of graphing the RRD files it produces. We’d like a desktop application that would open and graph the files, not something that runs on the server and displays the graphs in a web interface.

If no desktop apps exist, the next best thing would be to run the graphing webserver app in a VM on one of our local servers, but I’d like some advice as to the effectiveness of that.

If that would be ineffective, we would then consider changing from CollectD to something that logs, stores, and graphs the data through a webserver. We have looked at Munin in the past. Is Munin lightweight? What other low-impact applications are there?
