A single circle follows the mouse cursor within an SVG canvas. The visualization demonstrates pointer tracking in React, using state to store the current mouse coordinates and updating the circle's `cx` and `cy` attributes on every mousemove. The code uses React’s `useState` and `useCallback` hooks, with the SVG rendered directly via ReactDOM. D3 v7 is loaded but not actively used, as the rendering relies purely on React’s declarative SVG elements. The mouse position defaults to the canvas center before any movement.

Circle following Mouse

A circle follows the cursor’s position across a 960x500 SVG canvas. Built with React and D3 v7, the example uses an `onMouseMove` event handler on the `<svg>` element to capture mouse coordinates and update React state. The circle’s `cx` and `cy` attributes are bound to this state, causing the circle to continuously reposition as the mouse moves. The SVG is rendered via React’s `ReactDOM.render`, with the circle radius fixed at 30 pixels.

Follow mouse with circle.

A circle follows the mouse as it moves across an SVG canvas. The demonstration uses React state to track cursor coordinates on mouse move and updates the circle’s position accordingly. Built with React 17 and D3 v6, the visualization relies on React’s `useState` and `useCallback` hooks, while the SVG circle’s `cx` and `cy` attributes are bound to the current mouse position.

Mouse following Circle

This example shows a single circle that follows the mouse cursor as it moves over an SVG canvas. The circle’s center coordinates are updated on every mouse movement event, re-rendering the shape in real time. Built with React, it uses the `useState` hook to manage the mouse position and an `onMouseMove` handler on the SVG element. The visualization demonstrates a straightforward interaction pattern, rendering with ReactDOM and the SVG namespace, with no data source involved.

Mouse follower

A circle tracks the mouse cursor across an SVG canvas, reacting instantly to movement. The visualization demonstrates state management in React, using the `useState` hook to store cursor coordinates and `useCallback` to optimize the mouse-move handler. The SVG circle updates its `cx` and `cy` attributes based on those coordinates, rendered via ReactDOM. The example uses D3.js v7 only for its bundled build, while the core interaction is purely React-driven.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, centering itself on the pointer’s coordinates. The example demonstrates React state management to track mouse movement, updating the circle’s position on every move event. It uses React’s `useState` and `useCallback` hooks alongside D3 v6 for the SVG rendering, with an initial circle centered at 480, 250. The visualization responds interactively in real time, showcasing a minimal integration of React and D3 for dynamic graphics.

Follow mouse with circle

A circle follows the mouse cursor across an SVG canvas as the pointer moves. The visualization uses React state management with `useState` and `useCallback` to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes on every mouse move event. Rendering is handled declaratively with React's JSX, creating a single SVG circle element that responds to pointer interaction. The example demonstrates basic event handling and state-driven updates in a React-based SVG visualization.

Mouse follower

A circle drawn with SVG follows the mouse cursor across a 960 by 500 pixel canvas. The visualization tracks the pointer's absolute client coordinates on every mouse movement event, updating the circle's center position accordingly. Built with React, the example uses the `useState` hook to store the current mouse position and a `useCallback` handler to update it, while the circle itself is rendered as an SVG `<circle>` element. The code relies on React 18 and D3 v7 only for DOM rendering, with no data or additional D3 visualization APIs involved.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.
