Love this! Would be super interested in any details the author could share on the data engineering needed to make this work. The vis is super impressive but I suspect the data is the harder thing to get working.
The most time and energy has been getting my head around the source data [0] and industry-specific nuances.
In terms of stack I have a self-hosted Dagster [1] data pipeline that periodically dumps the data onto Cloudflare R2 as parquet files. I then have a self-hosted NodeJS API that uses DuckDB to crunch the raw data and output everything you see on the map.
