Nice... Not a tool I'm familiar with. (I heard somebody rambling about
it a while back though.)

Perhaps you mean "WHNF"? :-P

Well, as you can see from the source code I included, it's not exactly hard
to use :)

Even a simple 16-color GIF is only 32,518 bytes, and that's without even
trying hard or losing the AA on the arrows. :-)

Me neither, but it certainly is noticeable. I wonder if you use just
horizontal and vertical lines, rather than diagonal lines, and don't use
rounded boxes, or a coloured background, or AA text, how that would affect
the file size?

Probably makes the file a lot smaller because it compresses better that
way.

I imagine if I were somehow able to generate an SVG version, it would be
many, many times smaller than any compressed bitmap.

...and yet it's taken me this long to download and install the thing! ;-)
I see what you mean about a mess. Even with a very simple, almost
trivial graph, the produced layouts are extremely suboptimal. (Nodes on
top of each other, edges that consist only of arrow heads, absurdly long
edges for no reason, etc.) All of the graphs could trivially be improved
by just moving a few nodes to one side or another by a very small
amount. And it doesn't seem to matter which layout engine I use; they
all seem to produce hopeless layouts.
Still, it *is* much faster than doing this stuff by hand! ;-)
OOC, do you have any idea how I make it draw the edges as splines? I
have tried and tried and tried to make it do this, but it won't.

Um, splines=true? (graph property)
splines=boolean. Setting this to true causes edges to be drawn as
splines if nodes don't overlap. The default is false.
Also try concentrate=true.

Yeah. I did that. It has no effect. (The manual says it should work, but
it doesn't.)

Mmm, OK...
