Mouse Follower

Mouse Follower

A smiley face rendered in SVG follows the cursor inside a 960×500 viewport. The React component tracks mouse movement via the `onMouseMove` handler and updates the circle’s position using state and the `useCallback` hook. The face is drawn with a yellow circle and two black eye circles, though the eyes remain static while the entire group moves. Rendering relies on React DOM with SVG elements, and the example highlights state-driven updates without external data sources.

A smiley face follows the mouse cursor across the screen, rendered as a single SVG circle that moves in real time. The React component tracks pointer coordinates via the `onMouseMove` event handler, updating state with `useState` and `useCallback` to reposition the circle’s center. The visualization uses React DOM to render the SVG element directly to the page, with the circle’s radius fixed at 30 pixels. No external data sources are involved; the interaction is purely based on mouse position.

A smiley face drawn in SVG follows the cursor as it moves across the viewport. React manages the circle’s position via the `useState` and `useCallback` hooks, updating `cx` and `cy` attributes on every `onMouseMove` event. The example uses React 16.9 and renders directly into a full-screen SVG element without any data source.

A smiley face built with React follows the user’s cursor across a full-screen SVG canvas. The component uses React’s `useState` hook to track mouse coordinates, updated via the SVG `onMouseMove` event, and renders a circle element centered on those coordinates. The visualization demonstrates unidirectional data flow with a blank viewport and no additional data source.

This example shows a smiley face rendered as an SVG that follows the mouse cursor across the full browser viewport. The React component tracks the pointer position through an `onMouseMove` event handler on the SVG element, updating the circle’s `cx` and `cy` coordinates via React state. The code uses React 16.9 with `useState` and `ReactDOM.render`, alongside core SVG primitives such as `<circle>` and `<g>`. The initial mouse position is centered at half the window’s width and height.

A smiley face follows the mouse cursor on an SVG canvas, with a yellow circle acting as the face and a smaller circle representing its mouth. Built with React and ReactDOM, the component tracks the cursor’s position via the `onMouseMove` event and updates state with the `useState` and `useCallback` hooks, re-rendering the SVG circle’s `cx` and `cy` coordinates accordingly.

Mouse Follower

A smiling face rendered as a React SVG component follows the mouse cursor across the full browser window. The face consists of concentric circles for the head, eyes, and mouth, all defined with static SVG properties. Using React 16.9 and ReactDOM, the component updates its position on every mousemove event, tracking clientX and clientY coordinates to re-render the graphic dynamically.

A smiley face follows the mouse cursor across a full-screen SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and stores them in state with the `useState` hook, updating the circle's `cx` and `cy` attributes through re-rendering. The `useCallback` hook memoizes the event handler, while rendering relies on React DOM and plain SVG elements with no external charting library.
