This example reads a CSV file of video game sales data from a public GitHub gist, originally sourced from Kaggle, and displays a plain-text summary of its size and structure. It shows the file’s approximate size in kilobytes, the row count, and the number of columns. The code uses D3.js v5’s `d3.csv` to parse the remote data and `d3.csvFormat` to measure its length, then writes the summary into a large `<pre>` element. Alternate commented approaches demonstrate `fetch` with `async/await` and `d3.csvParse`.
