Smiley Face Part III

This example uses React and D3 v7 to render a single SVG circle that follows the mouse cursor. The circle’s center coordinates are updated via React state on every mouse move event, using the `onMouseMove` handler. The code leverages D3’s `arc` module and React’s `useState` hook, with a fixed canvas size of 960 by 500 pixels. The result is an interactive smiley face that tracks pointer movement in real time.

Loading Data with React and d3

This example shows a React application that loads and renders a smiley face using SVG. The app tracks mouse movement and updates the position of a circle in real time, while also maintaining a click counter. It uses React hooks like `useState`, `useCallback`, and `useEffect` to manage state and side effects, with ReactDOM rendering the components. The SVG elements are drawn directly in JSX, and d3 is referenced for handling data loading in the broader context of the example.

Loading data with react & d3

A smiley face rendered as SVG is built from React components for the background circle, eyes, and mouth. The mouth is generated using the d3 `arc` function to create a path. The example demonstrates a modular approach to composing SVG elements, with React managing the component hierarchy and d3 providing geometry. The code imports React and uses `ReactDOM.render` to mount the application, while the page includes a video embed. The data loading aspect is not implemented, as the app renders a static face.

Loading Data with React and D3

This example demonstrates how to load and display data in a React component using D3’s `arc` generator, rendering an SVG smiley face. It uses React’s `useState` hook to track the mouse position and updates a circle’s coordinates on `mousemove` events. The code imports `arc` from `d3` and renders SVG elements with React, while loading external libraries via CDN.

interactive

A smiley face rendered as an SVG follows the user’s cursor across a 960×500 canvas. The React app uses the `useState` and `useCallback` hooks to track mouse coordinates from an `onMouseMove` event, updating a single circle’s `cx` and `cy` attributes in real time. The circle’s radius is fixed, with no additional facial features or animation. The visualization demonstrates basic interactive SVG rendering with React, where the data—the mouse position—directly drives the graphical output.

Smiley Face Part I

A yellow circle with a black outline and a black arc smile follows the mouse cursor across an SVG canvas. Built with React and D3 v7, the smile is generated using the `arc()` generator from D3, while React's `useState` and `useCallback` hook react to `onMouseMove` events. The circle renders as an SVG element at the cursor's current position.

Loading data in react

A React smiley face tracks the mouse, with its eyes rendered as circles that move based on cursor position. The application uses React's `useState` and `useCallback` hooks to manage and update the mouse coordinates, while `ReactDOM.render` displays the SVG output. The initial face is drawn with a yellow circle as the head and two black circles for eyes, all defined with explicit positions and radii in the SVG markup.

Smiley face Part 1

A yellow circle follows the mouse cursor across an SVG canvas, responding to pointer movement. The visualization uses React's `useState` hook and `onMouseMove` event to track the cursor position, updating the circle's `cx` and `cy` attributes with the current coordinates. The D3.js library and React bindings render the SVG element, with the D3 `arc` function imported but unused. The graphic demonstrates real-time coordinate mapping through React state management.
