The Python twin of typescript/examples/19-render-json. It reads a JSON graph spec (a file path argument, or - for stdin), builds the graph with identity transforms, and prints the deterministic rendering.

python3 python/examples/19-render-json/main.py python/examples/19-render-json/sample-spec.json

The output is byte-identical to the TypeScript example. See the TypeScript example's README for the spec shape.
