Arrow thickness


I'm new to this tool and ran the example files to check it out. But before I might start using this software, I want to know if it is possible to vary the make plots with varying arrow thickness. Since I will need to visualize the importance of certain pathways. In the example files there are just 0's and 1's in the matrices and I tried to simply change the values but it doesn't appear to have any influence.

Thanks in advance for your help!

Arrow thickness

I'm not sure what example files you are looking at, as the input to Graphviz uses the DOT language and not matrices. In DOT, you would use the arrowsize attribute to adjust the size of the arrowhead and/or the penwidth attribute to change the size of the edges.
