If given, this loop will be re-used, otherwise an appropriate one will be looked up or created.
If false (the default), the loop is meant to run in a separate thread and will be started if necessary. If true, the loop is meant to run in the thread this object is instantiated from, and will not be started automatically.
A helper to start and stop an IO loop in a controlled way. Several loop runners can associate safely to the same IO loop.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
