Loading and Parsing CSV

This example demonstrates reading a raw CSV file from a GitHub Gist and logging its contents to the browser console. The page uses the Fetch API within an asynchronous `fetchText` function to retrieve the text from the specified URL, then displays the raw CSV data via `console.log`. The code highlights a basic loading pattern, contrasting it with a commented-out "pyramid of doom" approach that chains `.then()` callbacks. No CSV parsing or visualization occurs; the example focuses solely on data retrieval and output.

A grid of fifteen smiling faces, each rendered as a yellow circle with black outlines, two eyes, and an arc-shaped mouth. The faces vary subtly in eye placement, eye size, and mouth thickness due to random parameters. Built with React and D3, the visualization uses SVG primitives, with the mouth path generated by D3's `arc` function. The `range` function from D3 creates the array of fifteen face components.
