This example demonstrates the initial steps of fetching and parsing a CSV file from a remote URL using the Fetch API. The page loads a data file containing named CSS colors and sets up a promise chain to handle the asynchronous response. The code begins by calling `fetch(url)` on the Gist-hosted CSV, then attaches a `.then()` method to process the response. The visualization itself is not yet rendered, as the focus is on establishing the data loading workflow that will subsequently parse and display the color information.
