treeplotter

Tree plotting is really hard in Python. The treeplotter package aims to make the process easier. It wraps the TreantJS library to plot trees and saves them to a rendered HTML file. This HTML file is then also exported to a high-res PNG by wrapping R's webshot package. The package requires some complicated installs, but this is the price to pay to not use any R, Javascript, or CSS ;)

Usage

This library has Node and Tree classes in the treeplotter.tree module. Node objects can store various items. We can then specify the node children and parents. A Tree is then defined by a root node. From this, we can create tree visualizations. See here for a complete demo.

This package is used in the decitala package (see here) to make FragmentTree diagrams, like the following one of the Greek Prosodic Feet:

Installation

The basic package can be installed with

$ pip3 install treeplotter

To create the tree diagrams, however, some additional installs are required. See here for the complete instructions.
