You can use indirect way to refer a source file as graph description.

Use this syntax: ![Alt text](https://g.gravizo.com/source/<custom_mark>?<url_source_url_encoded>). And use html comment or summary tag <details><summary></summary></details> (you can use html comments but some graphs uses -->) to hide the source followed by your description graph in DOT syntax, UMLGraph, PlantUML or SVG :

  digraph G {
    size ="4,4"
    main [shape=box]
    main -> parse [weight=8]
    parse -> execute
    main -> init [style=dotted]
    main -> cleanup
    execute -> { make_string; printf}
    init -> make_string
    edge [color=red]
    main -> printf [style=bold,label="100 times"]
    make_string [label="make a string"]
    node [shape=box,style=filled,color=".7 .3 1.0"]
    execute -> compare

This allows to include your graphs in the README and is still readable in a normal text editor.

SVG output it's ready. Only need to replace https://g.gravizo.com/g? by https://g.gravizo.com/svg? and https://g.gravizo.com/source? by https://g.gravizo.com/source/svg?
