A simple tree parser for trees in bracket notation written in python. For example the following code (with default values for fontdict and textkwargs explicitly specified)
from treeparser import TreeParser
import matplotlib.pyplot as plt
fig, ax = plt.subplots(1, 1, figsize=(20, 10))
string = "[C[C[C[C[C][C[G7[Dm7][G7]][C]]][G[G[D7[Am][D7]][G]][G[D7[Am[CM7][Am]][D7]][G]]]][C[C[Bo7[Dm[C#o7][Dm]][Bo7]][C]][C[G7[Dm7[FM7][Dm7]][G7]][C [C][C[G7[FM7[C7][FM7]][G7[G7[F#o7][G7[Fm6][G7]]][G7[G7[G64][G7[G47][G7]]][G7[G47[G64[F#o7][G64]][G47]][G7]]]]][C[G7[C64[C7][C64]][G7]][C]]]]]]]]"
parser = TreeParser(string, True)
parser.plot(ax=ax, padding=1, fontdict={'fontsize': 12}, textkwargs={'bbox': {'facecolor': 'red', 'pad': 10}, 'style': 'italic'})results in:
