Orientation needs a square option.

I have a Rails app with some 150 or so activerecord models. Neither vertical or horizontal orientation work well since there will be so much overlap between different lines since the output will either be absurdly long or absurdly high.

I believe a square option would work a lot better.

Thanks for the suggestion. Unfortunately we are dependent on the ranking algorithms provided by Graphviz. The rankdir option is used to either rank models from top to bottom or from left to right. I don't believe there is a way to distribute nodes differently. Of course if you have a suggestion how to implement it I'm all ears.

Ok. I suppose it is good enough for my use case to get a .dot and manually arrange the result. Thankfully I don't have to do it very often.

I wish we could revisit this idea and find a way... the PDF that I tried to print this morning had a page size of 10154 x 1315 mm (Landscape Custom)

using pdfposter, I got it to be split in 2 page high and 11 pages wide.
I would have prefered something like a 4x5

Thankfully with clustering found in #320
I could get a smaller pdf has a page size of 754 x 5887 mm (Portrait Custom)

still being able to precise some sort of limit would be great
