Example invocations of random_tree_demo.py

$ python3 random_tree_demo.py -h        
usage: random_tree_demo.py [-h] [-c] [--minh MINHEIGHT] [--maxh MAXHEIGHT]
                           [--maxb MAXBREADTH] [--ent ENTROPY] [--nohtml] [-v]
                           N

Demo tree generator

positional arguments:
  N                  number of nodes in generated tree

optional arguments:
  -h, --help         show this help message and exit
  -c, --compvals     compare values while colorizing tree
  --minh MINHEIGHT   min height of tree to be compared, default 1
  --maxh MAXHEIGHT   max height for each node (except root), default N
  --maxb MAXBREADTH  max number of childs for each node, default N
  --ent ENTROPY      dataset size. Default dataset is ascii letters. If
                     expected dataset size is bigger then ascii letters set
                     then it is extended with D_{n} where n is int
  --nohtml           if provided generates graphviz compatible serialization
  -v, --verbose      print to stderr time required to serialize tree (tree
                     generation step excluded)

Note: delete --nohtml flag from commands bellow and copy-paste output here to visualize generated graphs, or install graphviz to vizualize graph locally
