mouse

A smiley face drawn in SVG follows the mouse cursor across a yellow canvas. The React component uses the `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updating a circle's `cx` and `cy` attributes through the `onMouseMove` event. A `useCallback` hook memoizes the event handler for performance. The visualization demonstrates real-time interaction within a React-rendered SVG, where the circle's position directly mirrors the user's pointer movement.

Fork of Loading and Parsing CSV Data

This example demonstrates loading and parsing CSV data using D3.js v5 within a React framework. It fetches a CSS Named Colors dataset from a GitHub gist and processes it to display the file size, row count, and column count in a large text element. The code includes commented-out implementations using `d3.csv`, `d3.json` with promises, and modern `fetch` with async/await syntax, highlighting different approaches to handle asynchronous data loading.
