Fork of Smiley Face Part II

This interactive React visualization renders a single SVG circle that follows the mouse cursor across the full browser window. The circle’s position updates continuously based on the current mouse coordinates, using state management with React’s `useState` hook and event handling via `onMouseMove`. The app is structured with a full-window SVG canvas, and the circle’s radius is fixed at 30 pixels. The code imports React and ReactDOM, and the rendering is done through SVG elements, providing a minimal example of dynamic, mouse-driven graphics.

Loading and Parsing CSV Data

This example demonstrates how to load and parse CSV data from a remote URL using the Fetch API and asynchronous JavaScript. It fetches a CSV file containing CSS named colors and logs the raw text to the browser console for inspection. The code uses `fetch` with `async/await` to handle the network request and response, and includes a commented-out alternative using promise chaining. No parsing or visualization is performed; it focuses solely on the initial data-loading step.

Fork of Let's Make a Face Part II

This example shows a grid of eighteen randomly generated smiley faces, each rendered as an SVG composed of a yellow circular background, two eyes, a mouth, and teeth. The code uses React components for each facial feature and leverages the D3 arc generator to create the smiling mouth shapes. Faces vary in eye radius, mouth radius, smile width, and mouth width, producing a playful collection of distinct expressions. The visualization is built with React and D3 v7, with each face drawn using SVG elements within a transformed group.
