This example demonstrates how to load and parse CSV data using D3 v7. It displays the row count, column count, and file size in kilobytes as large text on the page. The code uses `d3.csv()` to fetch and parse a CSV file from a GitHub gist, then processes the resulting data array and columns. It also includes commented-out alternatives using `fetch()` with `async/await` and `d3.csvParse()` to illustrate older parsing approaches.
