This example demonstrates how to load and parse CSV data using D3.js v7 within a React framework. The page displays a message showing the data's size in kilobytes, row count, and column count after fetching a remote CSV file via `d3.csv`. The data source is a GitHub Gist containing CSS color values, rendered alongside an embedded SVG illustration of a city scene. The visualization uses D3's asynchronous data-loading capabilities to read the CSV and parse it into an array of objects, with the results displayed in a styled HTML `<pre>` element.
