A tool for working with compiler graphs 

Free software with a MIT License

This is a snapshot ot the sources seafoam-master.zip

Todo: add howto and document
The program is reading binary graph data from graal compiler software and vm
translating that with few options into graphviz data then running dot

But only need to add a parser for that binary graph data to gml4gtk
and there is a GTK+ gui tool somewhat similar as igv without graphviz dependacy
