Does anyone know of a software package for the Mac which can do specialized
drawing.  I'm looking for something which can do the following type drawings:

ORGINIZATIONAL CHARTS (traditional/Matrix)
TIMELINES (the ones with triangles for start/end)
ETC..

I relize any graphics package like CANVAS, MacDRAW can handle these mundane
tasks,  but I'm looking for a package which makes this task easier. I would
really like to be able to do things like import a list of tasks and a list of
durations and have the package automatically draw a timeline scaled to fit
on one page with the lines correctly relating to the duration in some units (weeks, days, months).  Does any one know of such a beast???  I find that even
making a template in a program like CANVAS is still difficult to "fill out"
with data and align so that it doesn't look like a five year old did the work.
(Maybe my drawing capabilities are that bad :^)


I guess this falls under... I wish it was easier to...

Any suggestions??
