Aleksey,
Have you looked at grap? I looked in the troff manual I have (Text
Processing Dougherty and O'Reilly) and it isn't inj there but it is in
my Eroff manual. Eroff is an enhanced troff product we use on SCO but I
believe it is on another flavor of UNIX but there is no LINUX version. I
did a search and it looks like it is in groff. I never used it but it
does graphs so you are looking for a pie chart which it might do. 

Hope this helps.

Hi.  I'm looking for a way to automatically generate a graph from a
nested list.

For example, here is a list:

1
    2
    3
4
    5
    6
    7

And here is the graph:

http://www.verticalsysadmin.com/crude_drawing.png 

I want the top level elements closest to the center of the circle, and
I want the sub-elements removed from the circle, but I want the graph
to show the relationship between elements and their children.

I have a very large outline to handle (over a hundred elements in all)
and I need to visually represent it in a (relatively) compact way that
will clearly show the hierarchy -- it's my way of tackling the depth
vs. breadth problem in knowledge management -- I want to be able to
quickly and efficiently navigate depth vs. breadth while still keeping
track of the big picture.

(The specific application is in aligning goals, plans, projects and
tasks, but if successful this could have wider application.)

I don't want to hand-draw the circles, sectors, and partitions of
sectors, especially since the outline is updated constantly and I
don't want to manually redraw the thing.  And I want it to look neat
and sharp -- I want the computer to draw it.

Is there something out there that will do this?

Cheers,
Aleksey
