This example loads a CSV file of CSS named colors using d3.csv and displays basic metadata about the dataset in large text. It reports the file size in kilobytes, the number of rows, and the number of columns, computed with d3.csvFormat and the data's columns property. The visualization relies on D3 v6’s promise-based CSV parsing and DOM manipulation via document.getElementById. A commented-out alternative demonstrates the equivalent approach using fetch, async/await, and d3.csvParse.
