No pulldown menu

Hi,

I'm testing this out and noticed that the pulldown menu that was shown in the screenshots for selecting the levels to plot is no longer visible. The page has to be reloaded if you want to switch to a different level.

Thanks for the note @aparente-nurix - I should probably add a note on the main readme, but this repo is basically for tutorial purposes but not recommended for real uses ever since we added sunburst to plotly.js / plotly.py / dcc.Graph https://plotly.com/python/sunburst-charts/
