This example displays a simple black-and-yellow polygon above a heading and a text block that reports statistics about a CSV file loaded from a GitHub gist. The page uses D3 v5 to fetch the remote CSV data with `d3.csv`, then computes and formats the file size, row count, and column count using `d3.csvFormat` and the `data.columns` property. The SVG polygon is styled via CSS, while the embedded YouTube video describes the project’s process. The visualization primarily demonstrates asynchronous data loading and basic text output rather than complex visual encoding.
