This example demonstrates how to load and parse CSV data using D3 v7, displaying the dataset’s file size, row count, and column count in a large text pre element. The code fetches a CSV file of CSS named colors from a GitHub gist via `d3.csv`, then formats the parsed data with `d3.csvFormat` to calculate its kilobyte size. It also reports `data.length` for rows and `data.columns.length` for columns, providing a concise summary of the loaded dataset’s structure.
