This example demonstrates how to load and parse CSV data with D3. It displays a summary message showing the data size in kilobytes, row count, and column count. The code uses `d3.csv` to fetch and parse a remote CSV file containing CSS named colors from a GitHub gist. It also calculates the formatted data length with `d3.csvFormat` and accesses rows and columns through the parsed data object’s `length` and `columns` properties.
