Cheops and Cheops-ng replacement?

[Tink]

I used Cheops ages ago to do a graphical diagram of a network I was working on. I am looking to do the same thing again but I was wondering if there were other programs out there that I can take a look at. Looking for something that runs on Linux, must be free, and organizes the data well.

If you are wondering what I am talking about here is the link to there screenshot page
