Error in angular/graph_coloring example

[rtaupe]

When running
clinguin client-server --domain-files examples/angular/graph_coloring/encoding.lp examples/angular/graph_coloring/instance.lp --ui-files examples/angular/graph_coloring/ui.lp --backend=ClingraphBackend --clingraph-files=examples/angular/graph_coloring/viz.lp
as suggested in https://github.com/potassco/clinguin/blob/master/examples/angular/graph_coloring/README.md,
I get the following error:

The same happens also with the other examples with ClingraphBackend.

Hi @rtaupe sorry for taking so long to get back to you. This needs an update in clingraph, just make sure you have the latest version and that should fix the issue.
