A red circle follows the mouse pointer across an SVG canvas, with its radius dynamically linked to touch contact size when interacting via touchscreen. Built with React and ReactDOM, the visualization uses state management via `useState` and `useCallback` hooks to update the circle’s position on mouse and touch events. The code imports React 16.9 from a UMD bundle and renders fully client-side, displaying the current touch radius as text while the circle responds to pointer movement.

Mouse Follower

An interactive SVG circle follows the mouse cursor across a 960x500 canvas. The React application tracks pointer movement via the `onMouseMove` event handler, updating the circle's center coordinates with each `clientX` and `clientY` value. Using `useState` for position state and `useCallback` to optimize the event handler, the code renders a single red circle (radius 30) whose position updates in real time. The example demonstrates a basic React-D3 integration, with the visualization rendered entirely through React's declarative SVG output.

Mouse follower

A red circle follows the mouse cursor across a full-screen SVG canvas, with its center position updating in real time to match the pointer coordinates. The visualization uses React hooks (useState and useCallback) to manage the cursor position state and handle mouse movement events. The circle’s coordinates are bound directly to the mouse event’s clientX and clientY values, and the SVG viewport spans the entire browser window.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves. Built with React and D3 v5, the app uses React’s `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle’s `cx` and `cy` attributes accordingly. No data source is involved; the visualization simply demonstrates interactive event handling and state-driven rendering with SVG.

Mouse follow

A circle follows the mouse cursor across an SVG canvas. The visualization demonstrates real-time interaction tracking, with the circle's position updating instantly on every mouse movement. Built with React, the app uses the `useState` hook to store cursor coordinates and the `useCallback` hook to handle the `onMouseMove` event, then renders the circle as an SVG `<circle>` element with dynamically updated `cx` and `cy` attributes.

Follow Mouse

A circle follows the mouse cursor across an SVG canvas, centered on the pointer's current position. The visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, updating the circle's `cx` and `cy` attributes accordingly. Rendered with React and D3 v6 in an SVG element, the example demonstrates simple interactive state management without any data source or external datasets.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas, with its position updating in real time. Built with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates on a dedicated SVG `onMouseMove` event handler. ReactDOM renders the SVG, and the circle's `cx` and `cy` attributes update live as the pointer moves.

Mouse Follow

A circle in an SVG follows the mouse cursor in real time. The visualization uses React’s `useState` and `useCallback` hooks to track pointer coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes. Rendering is handled by ReactDOM, which mounts the SVG element defined in the component’s JSX. The example demonstrates a simple, interactive state-driven update with no external data sources.

Mouse follow

A moving circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The example uses React state management with the `useState` and `useCallback` hooks to track cursor coordinates, and renders the circle via SVG elements in a React component. Mouse move events trigger updates to the circle's center position, initialized to the middle of a 960×500 viewport. The visualization demonstrates a simple interactive pattern using React's declarative rendering and event handling.
