Language to build network topology diagram from data

I have all the underlying topology data, I wrote a Perl script to collect it and organize it. The script will run every so often and automatically and I'd like to build a diagram of the current network device relationships to include the interfaces. I need to display it somehow. It will be displayed on a web server, so either web code or an image would do just fine. I was looking at google charts but none of the options really suit a topology diagram (aside from Org Chart perhaps?!?). The server already utilized a bunch of google charts.

I have experience with a number of different languages, and I could build it in swing but that seems ridiculous..

Are there any chart libraries out there that I could simply dump data into in js table or JSON?

Thanks ahead
