Is there a web front end for arbitrary RRD files?

Hey /r/linuxadmin,

I am creating RRD files with standalone software and I am looking for a web front end to help manage them. Some features I am looking for are graph creation, (pick colors, durations, etc) and zooming/panning capability.

From previous projects I am fairly sure cacti is capable deal with arbitrary RRD files. Collecdweb looks like it might be capable as well with minimum code adjustment.

Before I dive in head first I wanted to check here to see if there are any other options. Thanks!
