Howdy,
about this omni graffle /reunion/canvas- writing a family flow chart

you could have a look at Curio - great looking OS X software - you can draw, type, what ever in it
it can export you project in html, pdf or as image ( whole or selected parts)

I use it for sorting out ideas, design etc
costs $90 US i think
 30 day demo available
