A React component renders an SVG circle that follows the mouse pointer across a 960×500 viewport. On every mouse move, the `onMouseMove` event handler updates the circle’s `cx` and `cy` coordinates via React’s `useState` and `useCallback` hooks. The circle starts centered and has a fixed radius of 30 pixels. The example demonstrates interactive SVG rendering with React, using only ReactDOM and no external data or visualization libraries.

Mouse follower

A React component renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel canvas. The circle starts at the center and updates its position on every `mousemove` event via React's `useState` and `useCallback` hooks. The `handleMouseMove` callback reads the event's `clientX` and `clientY` coordinates to set the new circle center, using ReactDOM to mount the app. No data source is involved; the visualization simply tracks pointer movement in real time.

Mouse follower

A circle follows the cursor as it moves across an SVG canvas. The example uses React’s `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. The SVG’s width is fixed at 960 pixels and height at 500, with the initial position centered. The rendering is done entirely through React’s declarative component structure, producing a simple interactive visualization without any external data sources.

Mouse Follower

A React component renders an SVG circle that tracks the mouse cursor across a 960-by-500 viewport. The circle’s position updates in real time through React’s `useState` hook and an `onMouseMove` event handler on the `<svg>` element, which captures the cursor’s `clientX` and `clientY` coordinates. The example demonstrates interactive SVG rendering with React 16.9, using the `ReactDOM.render` method to mount the application, and relies on a production build from unpkg. The circle maintains a fixed radius of 30 pixels while following the pointer.

Mouse follower

A React application renders a single SVG circle that continuously follows the cursor across a 960-by-500 viewport. The component tracks mouse movement via React’s `useState` and `useCallback` hooks, updating the circle’s `cx` and `cy` attributes on every `onMouseMove` event. Using the `ReactDOM` API to mount the app, the visualization demonstrates declarative state management for real-time interaction without external data sources or animation libraries.

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 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 renders an SVG circle that follows the mouse pointer across a 960 by 500 viewport. The circle’s center coordinates are updated via React’s `useState` hook and a `handleMouseMove` callback attached to the SVG’s `onMouseMove` event. The `useCallback` hook memoizes the event handler, and `ReactDOM.render` mounts the app. The visualization demonstrates basic state-driven interactivity without external data, using only React and SVG primitives.

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.
