I'm using the following command to generate the graph:
cat mapper.dot | circo -Tpng >output.png
Where mapper.dot is a file with the above content.
The problem is that there is way to much space between the nodes. And I mean way to much. Is there some way to decrease the space?
Judging by the output from your dot file, I'm not sure whether circo is the way to go. Personally I would use sfdp instead.
If I remove your uuoc and create the image with the following command:
sfdp -Tpng -Goverlap=false -o output.png mapper.dot
You will get shorter edges with no node overlap, but on the other hand, edges will overlap with nodes. To get away from this, you could enable splines by adding
-Gsplines=true
to the command.
The output is nowhere near perfect, but to me it looks a bit more appealing than before.
