This example displays a large pre-formatted text message reporting the size, row count, and column count of a CSS Named Colors dataset loaded from a CSV file. It uses D3 v5’s `d3.csv` promise-based function to fetch and parse the remote CSV, then formats the summary using `d3.csvFormat` and `data.columns.length`. The visualization is minimal, focusing on parsing and data introspection rather than graphical rendering, with commented-out alternatives using `fetch` and async/await.
