DOT gives “triangulation failed” error

问题

I have a .dot file and I am using command line to plot a graph using the dot file in pdf format using the following command

$ dot -Tpdf -O output_model.dot

I am getting the following error:

libpath/shortest.c:315: triangulation failed libpath/shortest.c:183: source point not in any triangle.

Any ideas why am I seeing this error?

回答1:

Without seeing the contents of your .dot file it is difficult to know. But, I've had a similar error when using the constraint=false parameter on the edges in a graph.
