ocamlgraph-editor binary package in Ubuntu Bionic s390x

 Ocamlgraph editor is an interactive graph editor for GNOME; it is based
 on hyperbolic geometry (it "zooms" more on graph nodes which are in the
 center of the editing area and zooms less on periferic nodes).
 .
 Ocamlgraph editor works with the following file formats to load and
 save graphs: GML (Graph Modelling Language), DOT (the file format used
 by Graphviz).
 .
 Ocamlgraph is still to be considered experimental.
