Rankdir ignored when drawing
I am trying to make the following digraph face a different direction, from top to bottom, instead of left to right. I have placed rankdir=tb and rank=same for the nodes I would like to be together, but I cannot get the wanted result (which you can see here). Does anyone know why this is happening? The source is directly provided from pygraphviz.

Solution
Can you show what the desired graph should look like, from your description I do not understand well, I can assume that this is it:
The way I achieved it was this:
- I removed
rankdir=tb,becausedotengine by default is top-down. - I removed all
graph [rank=same];but for vertical leveling I usedgroupattribute, I added two groupsg1andg2for separate graph to two vertical columns. - I changed
ranksepto2to add a little more length to the edges.

Variant №2 (horizontal branch)
Since the graph is located from top to bottom, you can give nodes the same rank ({rank=same; node1; node2; ...; nodeN}) for the horizontal arrangement.
Variant for partially horizontal branch, need to specify that the two nodes ("computerVisionPipeline.multiDepth.reconstruction","computerVisionPipeline.multiDepth.normalization") have the same rank. To do this, add the following lines:
...
{
rank=same;
"computerVisionPipeline.multiDepth.reconstruction";
"computerVisionPipeline.multiDepth.normalization";
}

Variant with full horizontal branch, need to specify that the three nodes ("computerVisionPipeline.multiDepth","computerVisionPipeline.multiDepth.reconstruction","computerVisionPipeline.multiDepth.normalization") have the same rank. You can also adjust the edge length with the minlen attribute.
