The only tool that I knew that could do this kind of work (on Linux) was Dia. Although it has a lot of features it seems (I’m not sure, since I’ve only used it once) that there aren’t much sheets available to download, and I don’t like the ones provided by default.

Later I’ve decided to look for another program, and I’ve found Kivio an easy to use diagramming and flowcharting application integrated in The KOffice Project.

Kivio provides by default a couple of nice sheets, so let’s hope it works as expected.
