This example displays a single yellow circle that moves with the mouse over a fixed SVG canvas. The circle’s center coordinates are tracked by React state, updated via an `onMouseMove` event handler on the SVG element. Using React’s `useState` and `useCallback` hooks, each mouse movement re-renders the circle to the new position. The SVG is generated through ReactDOM rendering, with a reactive drawing that directly mirrors pointer location.

Fork of Smiley Face Part II

This example shows a single yellow circle that moves across an SVG canvas in response to mouse movement. Built with React 16.9.0 and rendered via SVG, the circle is positioned using the `clientX` and `clientY` coordinates from the `onMouseMove` event, with initial state centered at (480, 250). The code uses React's `useState` hook to track mouse position and the ReactDOM `render` method to update the circle's `cx` and `cy` attributes dynamically.

Fork of Smiley Face Part II

This example shows a single yellow circle that follows the cursor across an SVG canvas, updating its position in real time based on mouse movement. Built with React and rendered as SVG, it uses the `useState` hook to track the mouse coordinates and the `useCallback` hook to handle `onMouseMove` events. The circle’s `cx` and `cy` attributes are bound to the current mouse position, and ReactDOM renders the component into a root element, with the canvas sized at 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.

Fork of Smiley Face Part II

This example shows a yellow circle that follows the mouse cursor across an SVG canvas. Built with React, it uses the `useState` hook to track mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event. The circle’s position is updated by setting the `cx` and `cy` attributes based on the pointer’s client coordinates. The visualization is rendered using React’s `ReactDOM.render` into a root element, with SVG as the output format.

Fork of Smiley Face Part II

A single yellow circle tracks the mouse across a full-window SVG canvas. The example demonstrates React state management with the `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` coordinates on every `mousemove` event. Rendered with ReactDOM, it uses plain SVG circle elements without external visualization libraries. The code begins with an unused static smiley face layout, replaced by an interactive circle following the cursor.

Fork of Smiley Face Part II

A yellow circle follows the mouse cursor across a blank SVG canvas. The visualization uses React with hooks, specifically `useState` and `useCallback`, to track mouse coordinates from an `onMouseMove` event listener on the SVG element. The circle’s center position updates dynamically via React state, rendering through `ReactDOM` in a fixed 960×500 viewport. No external data source is used; the interaction is driven entirely by local pointer events.

Fork of Smiley Face Part II

A fork of the Smiley Face Part II example renders a single black circle that follows the mouse cursor across a yellow SVG canvas. Built with React and SVG, the app uses the `useState` hook to track mouse coordinates and the `onMouseMove` event to update them. The circle’s position is bound to the current `mousePosition` state, while its radius remains fixed at 40. The code relies on React’s `useCallback` for the event handler and renders the visualization via `ReactDOM.render`. No data source is used; interaction drives the display.

This example shows a single circle that follows the user's mouse movement across an SVG canvas. Built with React 16.9 and rendered as SVG, the application uses the `useState` hook to track the mouse’s client coordinates and the `useCallback` hook to handle the `onMouseMove` event, updating the circle’s center position in real time. The visualization demonstrates interactive state management within a React component.
