This example demonstrates fetching a CSV file containing CSS named colors from a remote GitHub gist and parsing it with D3.js (v5). The page displays a large static “Hello HTML!” message, while the JavaScript console logs the number of parsed data rows using `d3.csvParse` on fetched text, and also logs the column count and formatted CSV length via the `d3.csv` function. The code uses the Fetch API for async requests and D3’s CSV utilities to handle the data.
