This visualization demonstrates how to load and parse CSV data using D3.js. It displays a headline and a message stating the data size in kilobytes, the number of rows, and the number of columns from a remote CSV file. The example uses D3.js v7's `d3.csv` function to fetch and parse the data, then `d3.csvFormat` to calculate its length. The data source is a GitHub Gist, and the page also includes an SVG image.
