This example shows a simple web page that loads a CSV file from a GitHub gist and displays summary statistics about it, including the file size in kilobytes, the number of rows, and the number of columns. The React app fetches the data using `d3.csv` and formats the output with `d3.csvFormat` in the message function. The SVG face components, built with React and D3’s `arc` API, are defined but not rendered in the final output, which instead presents the text summary in a `<pre>` element.
