ArrowTransmuterBase and its derivatives are used to make a fancy arrow around a given path. The __call__ method returns a path (which will be used to create a PathPatch instance) and a boolean value indicating the path is open therefore is not fillable. This class is not an artist and actual drawing of the fancy arrow is done by the FancyArrowPatch class.
Arrow Transmuter Base class
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
