This example demonstrates how to load and parse CSV data into a usable format, displaying the result as a text summary of file size, row count, and column count. It uses the D3.js `csv` function to fetch and parse a remote CSV file of CSS named colors, then formats the parsed data with `d3.csvFormat`. The interface includes a file input for user-selected local CSV files, triggering the same parsing workflow via the `onchange` event handler.
