This example demonstrates how to load and parse CSV data, displaying a summary of the dataset’s size in kilobytes, row count, and column count. It fetches CSS named colors from a GitHub gist and processes the data using `d3.csv` with promises in D3 v5. The code includes commented alternatives using `fetch`, `async`/`await`, and `d3.csvParse`, illustrating different asynchronous approaches. The result updates a plain text element, showing the parsed data’s dimensions without any chart rendering.
