Ranks and Subgraphs To work out the layout, Graphviz uses a system it calls “ranks”. Each node is assigned a higher rank than the highest ranked node that point to it. If your rank direction is set to left to right ( rankdir=LR ), then nodes with a higher rank are placed further to the right.

What does the size attribute do in GraphViz?
The size attribute lets you recommend a maximum or desired height and width for the output image in inches. I.e., the attribute size=3,5 tells Graphviz to generate a 3 by 5 inch image at most. If the image is smaller than 3 by 5 to begin with, Graphviz will leave it alone.

What is the default DPI value for GraphViz?
Well, Graphviz’s default DPI value is 96 pixels per inch. At that resolution a 3 by 5 inch image is a 288 by 480 pixel image. The layout engine has simply scaled up the image until at least one of the dimensions matched the desired size. You can override the default DPI value using the dpi attribute, like so: gvgen -dh3 | dot -Tpng -Gsize=3,5\\!
