_get_tree_stats(self)
Return a python list containing the statistics about the node tree:
0: number of nodes (tree size) 1: number of unique nodes 2: number of trapezoids (tree leaf nodes) 3: number of unique trapezoids 4: maximum parent count (max number of times a node is repeated in tree) 5: maximum depth of tree (one more than the maximum number of comparisons needed to search through the tree) 6: mean of all trapezoid depths (one more than the average number of comparisons needed to search through the tree)
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
