This example demonstrates the core steps of loading and parsing a CSV file with D3.js. It fetches a remote CSV containing CSS named colors from a GitHub gist using `d3.csv`, then calculates and displays summary statistics—file size in kilobytes, row count, and column count—within a styled `<pre>` element. The code also includes commented-out alternatives using the Fetch API and `d3.csvParse`. A separate `index.js` file shows importing from the D3 library and local ES6 modules, though it is not actively used by the main script.
