This example loads a CSV file containing CSS named colors from a remote URL and displays summary statistics about the dataset, including its size in kilobytes, row count, and column count. It uses D3’s `d3.csv` method to fetch and parse the data, then computes metrics from the parsed array and the `data.columns` property. The visualization also demonstrates alternative approaches with the Fetch API and `d3.csvParse`, though those paths are commented out in the code.
