useful: disk usage pie chart + graph visualization

I just wanted to tell you folks of two very useful free programs.

First, there is a disk usage pie chart browser, called JDiskReport. I was cleaning up my hard drive to prepare for a backup (I want to set up a RAID for the first time!), and I found it. It's free, and it has useful views like histograms of file distributions, modified distributions, other stuff I haven't looked. Plus if you want to look at a given directories distribution, you can just right click it and it's like one of those menu items. It's quite cool.

Anyway no I don't work for them I genuinely think it's just awesome, I wish windows would integrate the feature in their explorer. =p

Second, for those of you working with graphs, graphViz.org has an awesome graph visualization tool that we use for research. It has a very simple syntax and lots of examples.

Anyways, have a nice day. Just wanted to share some useful information! =p

From my own experience, I can confirm that Graphviz is an extremely useful tool for graph visualization. I have tested several other tools, and just before I was about to give up and write my own, I found Graphviz and have used it ever since.

I've never tried JDiskReport, but I use Gnome's baobab (which does the same thing -- a graphical pie chart) regularly. KDE also has filelight, which wasn't very good in KDE 3, but seems much better in KDE 4. Just in case you want another program which does the same thing. :)

I'll second (or third) that one. I use dot in a script to autmoatically output updated UML diagrams of my project - very handy.

I've only ever used dot second-hand, through kprof (for drawing profiling call trees) and doxygen (for drawing inheritance trees), but what I've seen of it, I like. :)

The useful program I've discovered today is khexedit, which is (not surprisingly) a hex editor. It sure beats the command-line hexedit, anyway.

dot and friends are great for small graphs, but the tools break down horribly on larger data sets. It's especially hard, for example, to get a graph where the edges don't cut over nodes (making the nodes unreadable). Even Visio has issues with this...

Various output formats also fail for unknown reasons. (The image outputters, such as .png, work reasonably well - it's other ones like .pdf that break easily.)

dot has a slight advantage over Visio in that it runs everywhere and its format is dead-simple.
