This example demonstrates how to load and parse CSV data using D3.js. It displays the file size in kilobytes, row count, and column count from an external CSV file fetched via `d3.csv`. The page also includes an SVG city illustration and uses HTML elements like `<pre>` and `<h1>` for text presentation. The code relies on D3 v7’s `d3.csv` and `d3.csvFormat` APIs to process the data asynchronously.
