This visualization reads a CSV file from a GitHub gist and displays basic metadata about the dataset as plain text in a large HTML `<pre>` element. Using D3 v7’s `d3.csvParse` and the Fetch API, it counts the number of rows, columns, and approximate file size in kilobytes. The output is then rendered into the page via `document.getElementById`, presenting a concise summary of the data’s structure without any graphical charts.
