Is there software to visualize project timeline data?

Question

I use WinDirStat to visualize my hard disk space and was thinking that it would be great to have something like that for some of the projects that I manage. Each project is broken up into parts with hours attached to those parts.

Is there any software out there that visualizes project data like this?

Answer 1

Deltek's project management software seems to do treemaps, according to this.

Here is the page of the Vision software.

Note: I know absolutely nothing about this software. I just found it with some googling.
