Circle Follower Mouse

Mouse Follower

A circle follows the mouse cursor within an SVG canvas. The visualization updates the circle's position in real time as the mouse moves. Built with React, it uses the `useState` hook to store the current mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event, updating the circle's `cx` and `cy` attributes accordingly. This example demonstrates interactive data binding and event-driven rendering in React with SVG.

A circle follows the mouse cursor across an SVG canvas. The React app tracks pointer movement via an `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. No external data is used; the visualization demonstrates real-time, state-driven rendering with React 16.9 and SVG.

Circle Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React and d3.v7, the app uses React’s `useState` and `useCallback` hooks to track and update the mouse coordinates on every `onMouseMove` event, rendering a single `<circle>` element with a radius of 30 pixels. The example relies on SVG rendering within a 960×500 viewport, with the initial circle centered at the midpoint of the canvas.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The React component uses the `useState` and `useCallback` hooks to track mouse coordinates from `onMouseMove` events, then passes those coordinates to the circle's `cx` and `cy` attributes. The visualization is rendered with ReactDOM into a 960×500 SVG viewport.

Mouse Follower

A circle follows the user's mouse cursor across an SVG canvas. The visualization uses React's `useState` and `useCallback` hooks to track the latest mouse coordinates and render a circle at that position. The circle's center updates on every mouse movement event, creating a direct and immediate visual response. The example is built with React 16.9.0 and ReactDOM to manage the SVG rendering and state updates.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas. The visualization demonstrates real-time interaction by updating the circle's center coordinates to match the pointer’s position. Built with React 16.9, it uses the `useState` hook to track mouse coordinates and the `onMouseMove` event handler on the SVG element. The rendering is handled entirely through SVG, with the circle’s `cx` and `cy` attributes updated on every mouse movement.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas, tracking the pointer's current position in real time. The visualization uses React's `useState` and `useCallback` hooks to manage and update the circle's center coordinates on every `onMouseMove` event, rendering the result as an SVG `<circle>` element. The initial position is centered in the viewport, and the window dimensions determine the SVG's width and height.
