Mouse Follower

Mouse Follower

A black circle follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's position and updates the circle's center coordinates in real time. The code leverages React hooks like `useState` and `useCallback`, with the `arc` function imported from d3, though only a standard `circle` element is rendered. The SVG's `onMouseMove` handler drives the interaction, displaying a simple, responsive pointer-tracking effect.

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.

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.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to manage mouse coordinates, with the `onMouseMove` event handler updating the circle's center. D3's `arc` module is imported but not used, while the SVG `<circle>` element is rendered directly through ReactDOM. The visualization demonstrates a simple interactive pattern without any data source or animation logic beyond direct mouse tracking.

A circle of 15-pixel radius follows the mouse cursor across an SVG canvas. The visualization updates the circle's center coordinates in response to mouse movement events, rendering through React's state management and the SVG element's event handling. The example uses a React component with a `useCallback`-wrapped mouse-move handler to update client coordinates, and D3's `arc` import, though it primarily relies on React's rendering for the visual output.

A single black circle follows the mouse as it moves across an SVG canvas. The React component tracks pointer coordinates through an `onMouseMove` event handler and updates the circle’s `cx` and `cy` attributes via React state. The example imports the `arc` function from d3 but does not use it, relying instead on plain SVG rendering and React’s `useState` and `useCallback` hooks for interactivity.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management with a `useState` hook and the `onMouseMove` event handler, which captures the cursor's client coordinates and passes them to the circle's `cx` and `cy` attributes. React re-renders the SVG element on each mouse movement, while D3's `arc` import is present but unused, and no external data source is involved.

A black circle follows the mouse cursor across a green SVG canvas, responding instantly to pointer movement. The visualization uses React’s `useState` and `useCallback` hooks to track the mouse position and update the circle’s `cx` and `cy` attributes. The SVG element’s `onMouseMove` event handler captures the cursor coordinates, while D3’s `arc` module is imported but unused. The example demonstrates a simple interactive pattern combining React state management with SVG rendering.
