Tree element showroom

This example showcases plot elements for tree styling in iplotx.

import matplotlib.pyplot as plt
import iplotx as ipx

tree = {
    "name": "Vertex\nlabel",
    "children": [
        {
            "children": [
                {},
                {
                    "children": [{}, {}]
                },
            ],
        },
        {},
    ],
}
tree = ipx.ingest.providers.tree.simple.SimpleTree.from_dict(tree)

fig, ax = plt.subplots(figsize=(3.9, 3.3))
