This example shows a smiley face rendered as an SVG circle that follows the mouse cursor inside a fixed 960×500 viewport. The code uses React’s `useState` and `useCallback` hooks to track the pointer’s `clientX` and `clientY` coordinates, updating the circle’s center position on every mouse move. The face itself is drawn with basic SVG `<circle>` elements—a yellow head and two black eyes—embedded directly in the React component’s JSX. Mouse tracking is handled via an `onMouseMove` event on the root SVG element, with ReactDOM rendering the entire interface.

Fork of Smiley Face Part II

This example demonstrates an interactive smiley face rendered as an SVG circle that follows the user’s mouse movement across the screen. Built with React (using hooks such as `useState` and `useCallback`), the application captures `clientX` and `clientY` coordinates from the SVG’s `onMouseMove` event and updates the circle’s center position accordingly. The visualization uses a production build of React 16.9.0, with the DOM managed via `ReactDOM.render` into a root div. The face itself is simplified to a single yellow circle with a black outline, with no static facial features visible.

Fork of Smiley Face Part II

This example shows an interactive smiley face built with React and SVG, where a single yellow circle follows the mouse cursor across a blank canvas. The application tracks the pointer’s `clientX` and `clientY` coordinates via React’s `useState` and `useCallback` hooks, updating the circle’s `cx` and `cy` attributes through the `onMouseMove` event. It uses React 16.9 and ReactDOM to render the SVG element, with a hardcoded width of 960 and height of 500 pixels. No external data source is involved; the visualization solely responds to user input.

This example shows a yellow smiley face drawn with SVG circles in React, where one circle follows the user’s mouse movements across the screen. The face includes two static eyes and a large yellow head with a black outline, while the nose moves dynamically. It uses React’s `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, re-rendering the circle’s `cx` and `cy` attributes. The visualization is built with React 16.9 and rendered as SVG, with a fixed canvas size of 960 by 500 pixels.

A single yellow circle follows the cursor across a full-window SVG canvas, its position driven by mouse movement events. The React component tracks pointer coordinates in state and re-renders the circle at the current location. The code uses React’s `useState` and `useCallback`, renders via `ReactDOM`, and updates an SVG circle element. The example demonstrates interactive mouse tracking in a React 16.9 environment.

This example shows a single unfilled circle that follows the mouse cursor across the full browser window, rendered as an SVG element. The circle’s center coordinates update continuously on mouse movement, using React’s `useState` and `useCallback` hooks to manage and optimize state changes. The visualization is built with React 16.9 and ReactDOM, rendering directly to the DOM, with the SVG’s `onMouseMove` event driving the interactive behavior. The underlying code includes commented-out static smiley-face circles, indicating the fork’s evolution from a fixed illustration to a mouse-tracking interactive graphic.

A circle follows the mouse cursor across an SVG canvas, with its horizontal and vertical position updated in real time to match the pointer’s coordinates. The example demonstrates state management in React, using the `useState` hook to store the cursor position and the `useCallback` hook to handle mousemove events. The `ReactDOM.render` method mounts the component to the DOM, while the SVG’s `onMouseMove` listener triggers updates, with the circle’s center assigned via `cx` and `cy` attributes.

Fork of Smiley Face Part II

A React application renders a single SVG circle that follows the mouse cursor as it moves across a 960×500 viewport. The circle’s position updates via React’s `useState` and `useCallback` hooks, which track the cursor’s `clientX` and `clientY` coordinates from the SVG’s `onMouseMove` event. The example demonstrates interactive rendering with React 16.9 and SVG, using a simple state-driven approach to update the circle’s `cx` and `cy` attributes in real time.

This example shows a smiley-face drawing built with React that tracks the user's pointer. A single circle follows the mouse cursor across the full browser window, rendered as an SVG element whose position updates in real time via React state and the `onMouseMove` event handler. The visualization uses React 16.9 and ReactDOM to manage the SVG circle's `cx` and `cy` coordinates, demonstrating interactive mouse tracking with a minimal, dynamic component.
