Mouse Follower

Mouse Follower

A React component renders an SVG circle that tracks the mouse position across a 960×500 canvas. The App uses the useState and useCallback hooks to store and update the cursor’s clientX and clientY coordinates on every mousemove event. The circle’s cx and cy attributes are bound to this state, making it follow the pointer in real time. The rendering relies on ReactDOM and SVG elements, with no external data sources beyond user interaction.

Mouse Follower

A React component renders an SVG circle that follows the mouse cursor across a 960-by-500 viewport. The app uses React's `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, passing the updated position to the circle's `cx` and `cy` attributes. The visualization demonstrates basic event handling and state-driven SVG rendering in React.

Mouse Follower

A React component tracks the mouse position and renders a single circle that follows the cursor across an SVG canvas. The application uses React’s `useState` and `useCallback` hooks to store and update the mouse coordinates, which are passed as `cx` and `cy` attributes to the SVG circle element. The circle starts centered on a 960 by 500 pixel viewport and moves smoothly in response to `onMouseMove` events. The example demonstrates a simple interactive pattern with React and SVG without any external data sources.

Mouse Follower

A React application renders an SVG circle that follows the mouse cursor across a 960 by 500 viewport. The component uses React hooks (`useState`, `useCallback`) to track mouse coordinates via the SVG `onMouseMove` event, updating the circle's `cx` and `cy` attributes. The initial position is centered, and the circle responds to pointer movement within the SVG element. Rendering uses React DOM with the production build of React 16.9.0.

Mouse Follower

A full-screen React application renders an SVG circle that tracks the mouse cursor across the viewport. The component listens to the SVG’s `onMouseMove` event, updating React state with the cursor’s `clientX` and `clientY` coordinates, which are then bound to the circle’s `cx` and `cy` attributes. The circle has a fixed radius of 30 pixels, and the SVG dimensions match the browser window. React uses the `useState` and `useCallback` hooks to manage and optimize the position updates.

Mouse Follower

A React component renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel canvas. The application uses React state and the `onMouseMove` event handler to track cursor coordinates, updating the circle's `cx` and `cy` attributes in real time. It demonstrates a simple interactive visualization built with React 16 and SVG, where the circle’s position is bound directly to the user’s pointer location.

Mouse Follower

A React component renders a 960-by-500 SVG containing a single circle that follows the mouse cursor across the viewport. The circle’s center coordinates are tracked via React’s `useState` hook, updated on every `mousemove` event through a `useCallback` handler that reads `clientX` and `clientY`. The SVG element listens for the mouse movement, and the circle’s `cx` and `cy` attributes are bound to the current position state. The code uses React 16.9 and `ReactDOM.render` to display the interactive graphic.

Mouse Follower

A React component tracks the mouse position within an SVG canvas using the `useState` and `useCallback` hooks, rendering a circle that follows the cursor. The `onMouseMove` event handler updates the circle's center coordinates via `setMousePosition`. The SVG circle updates its `cx` and `cy` attributes in real time, demonstrating reactive rendering with React 16.9 and ReactDOM.
