Add interactive plot (Plotly.js)?

[Gabriel-p]

This would apparently require storing all individual cluster datafiles as .csv.gz instead of parquet because it is rather difficult to read parquet files on the fly.

Also: would this add any value? Basically it would replace the Colab notebook and allow playing with the data without leaving the page, but the Colab notebook does not seem to be much used (~3% of total events).
