Mnh. Annoyed now. There is now absolutely no way for me to draw my UML diagram with no crossing lines, and after I spent ages trying to make sure none of them crossed, too. (Well, it's remotely possible that eons more shuffling would provide a solution, but it's also very likely that it is now actively impossible to do.)

Also, they have left out the end time on one occasion on one of the lines of the input, so I have to do really ugly things with flags andy carrying around data instead of being able to do everything nicely and happily. I wouldn't mind if it just happened to be a feature and they did it everywhere, but no - it's just the one place. Grr.

Is it a planar graph? If not you can't draw it without crossings. If if it is, then I think there's a trivial embedding in the 2-d plane.

I have no idea what the term 'planar graph' connotes. Lots of boxes. Lots of arrows going everywhere. More than one arrow in and out of any given box. Want it to fit on one A4 page without being less than about four point text.

I'm suspecting a planar graph is one which can be displayed in the plane without crossing.

I suppose UML rules out the traditional trick of putting a little bump in one of the lines to show it's hopping over another without intersecting?

The not-drawing-it-by-hand does, anyway.

Would it be cheating to use something like GraphViz (http://www.research.att.com/sw/tools/graphviz/) ? AFAIR it can deal with UML diagrams.

No, but rather too complicated now I've just done it all in Dia.

Who is Flags Andy? ;-)
