Loading and Parsing Data

This example demonstrates the initial step of working with external data in a web page: fetching and displaying raw CSV content. It shows how to retrieve a text file from a GitHub Gist URL containing named CSS colors, then logs the complete text to the browser console. The code uses the Fetch API’s `fetch()` method along with `response.text()` to asynchronously load the data, and it includes an `async/await` wrapper function for cleaner handling. The example provides a simple, foundational pattern for data loading that can be extended for parsing and visualization.

Hello HTML

A grid of randomized smiley faces renders as SVG via React components, with each face composed of a yellow background circle, two eyes, and an arc-based mouth. The React app maps over a range of indices from d3.range to generate 18 faces, each with randomized properties for stroke width, eye position and radius, and mouth dimensions. The d3.arc API constructs the mouth path, while React Fragments avoid extra DOM nodes for the eye pairs. The rendering uses d3.v7 and React 17, with each SVG face centered within a 160-pixel viewport.
