This example shows the basic structure of a bank customer dataset by displaying three summary statistics: file size in kilobytes, row count, and column count. It loads a CSV file from a GitHub gist using `d3.csv` and parses the data, then formats the metrics with `d3.csvFormat` and `Math.round`. The results are rendered as large text inside a `<pre>` element. The visualization relies on D3 v5’s promise-based loading API to handle the asynchronous data fetch.
