Modified data_plot.py, tried other way to plot figure with switched axes properly in data_plot_2.py (correct plot, no globals), stopped printing struncture and added abspath in pydot_exmaple.py #3
Files are now executable, graf.py gets colormap.txt from folder input/, saves figures into folder output/ #3
ENH: Corrected data structure, added legend, labels, adjusted fontsize in gg.py, added pydot_example.py - script for generating CALLTREE #3
