Venn Diagrams with Dia ?
Hello Everybody I am currently discovering dia (newest linux-release) and I am very impressed by the possibilities one has with this powerful program. Due to the fact that I have to create some "Euler-Venn" diagrams (diagrams to display sets) for a student's script on mathematics I wonder if it is possible to create them with dia. I tried to draw a diagram in which two sets intersect themselves. Somehow it wasn't possible for me to create an object that represents the intersection set. Has anybody an Idea how I can use dia to create these Euler-Venn diagrams ? Has anybody experiences in creating that kind of diagrams with dia ?

Then you can bend the endpoints to look like the intersection set. With judicious use of grid you can make various sets match up. Unfortunately, beziergons cannot create perfect circles, but you can approximate it.

Re: Venn Diagrams with Dia ?
An alternative: Make the "universe rectangle". Make two circles, overlapping. Do dialogs...properties...draw background=no. You can stop there, label the regions, and be done. Or... Make a beziergon, with the control points at the intersecting lines of the two circles. Drag as best you can to match the curves. Change fill color.
