This example displays summary statistics for Marvel power data, showing the file size in kilobytes, row count, and column count in large text. It loads a CSV file from a GitHub gist using `d3.csv` and formats the output with `d3.csvFormat` to measure data size. The visualization also includes commented alternatives using `fetch` with async/await and `d3.csvParse`, demonstrating different loading approaches. The page renders statistics in a styled `<pre>` element using D3 v5.
