This package can be used to render the structure of org files as a weighted graph. The rendering leverages plotly and produces an html file. The color of the node is directly proportional to the amount of text the node and its children contain: the darker the more.
Download this repository and use
pip install /path/to/local/repository/
Just import the package and call drawGraph passing to it the absolute path of an org file.
import org_tree as ot
ot.drawGraph("path/to/org/file.org", "file_encoding")
