What great submissions did
This brief was reconstructed from the dataset contents in 2026 as part of the Playground audit. The original November 2021 challenge brief was not preserved as a separate file in the source archive, so the analytical angles above are inferred from the column list. See the corresponding /challenges/ entry on datadna.onyxdata.co.uk for examples of how participants approached the data.
