I am trying to visualise output from cmspam and have some problems with right tool for that job

I saw example with GraphViz but I am interesting in something similar to sankey like https://blogs.sas.com/content/sascom/2014/08/19/path-analysis-with-sas-visual-analytics/ and have problem with finding something similar in open source.

I will be grateful for any advice or suggestion

The diagram looks quite nice. It seems like a good idea for path visualization. But I also don't know how to generate such visualization. If you find something good please share it. Maybe other people know?
