This example visualizes the shape and size of e-scooter usage data from Denver, Colorado. Ascending and descending bar charts on either side frame a text summary that reports the dataset’s file size, row count, and column count. The bars are drawn using D3 v7’s `d3.select` and `append("path")` methods with manually constructed SVG path strings, while `d3.csv` fetches the remote CSV and `d3.csvFormat` calculates its byte length. The summary is displayed inside an HTML `<pre>` element, and the layout uses flexbox for centering.
