This example demonstrates the fundamental process of loading and parsing CSV data with D3. It fetches a remote dataset of CSS named colors from a GitHub gist and displays summary statistics about the file in a large text element. The visualization shows the data’s size in kilobytes, row count, and column count by using `d3.csv` to load and parse the data, then `d3.csvFormat` to measure its length, and `data.columns` to determine the number of columns. An alternative implementation using `fetch`, `async`, and `d3.csvParse` is also provided in comments but not executed.
