Can you add a unit-test and also add a changelog entry to docs/whats_new/v0.1.rst?

[aryan26roy]

Sure! Just getting used to the procedure for this repo.

Thanks for the PR! It mostly looks good minus a few nitpicks.

One last thing: Can you also augment the existing example in examples/ to show off the label feature? E.g. in https://output.circle-artifacts.com/output/job/e94330e9-bd6c-4d83-ae14-8ed903121326/artifacts/0/dev/auto_examples/visualization/draw_and_compare_graphs_with_same_layout.html#sphx-glr-auto-examples-visualization-draw-and-compare-graphs-with-same-layout-py it would be great to see some sensible titles of the different graphs.

You can build the documentation locally to test it out and what it looks like by following the Contributing.md doc. Lmk if you have any issues! You'll also want to fix the coding style using the relevant poetry run poe apply_format command as well (which runs black and isort in the background)
