This example displays text reporting the parsed size, row count, and column count of a CSS named colors dataset loaded from a CSV file. It uses the D3.js library (version 5) with both `d3.csv` to fetch and parse the remote data, and `d3.csvFormat` to compute its length. A React-based build script populates a large `<pre>` element in the HTML with the resulting summary. The visualization is minimal, focusing on the mechanics of asynchronous data loading via Promises rather than graphical representation.
