A circle follows the mouse cursor within an SVG canvas. The example uses React's `useState` and `useCallback` to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes on every `onMouseMove` event. The SVG and circle are rendered directly through ReactDOM, with no D3 visualization logic, though the D3 library is loaded in the page. The interaction is purely event-driven, with the initial circle position centered at width/2, height/2.

Mouse follower

A circle follows the mouse cursor in real time across an SVG canvas, highlighting the immediate connection between pointer movement and visual feedback. The visualization uses React state management, with a `useState` hook tracking the cursor's `clientX` and `clientY` coordinates, which are updated via a callback on the SVG's `onMouseMove` event. Rendered with React’s `ReactDOM.render`, the circle’s position transitions smoothly as the state changes, while D3.js is loaded but not actively used in the logic. The example demonstrates a simple, responsive interaction pattern.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, with React managing its position in real time. The component uses React’s `useState` and `useCallback` hooks to track pointer coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes accordingly. The example demonstrates a minimal integration of D3.js (v5) with React, where D3 provides no visual functions—only the SVG rendering is handled by React, and the circle radius is fixed at 30 pixels. The canvas is 960 by 500 pixels, and the initial cursor position starts at the center.

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.

Mouse follower

A circle follows the mouse cursor across an SVG canvas. The example demonstrates React state management for tracking pointer position and rendering a visual response. The component uses `useState` to store mouse coordinates and `useCallback` to handle the `onMouseMove` event, updating the circle's `cx` and `cy` attributes on each move. The SVG element listens for mouse events, and ReactDOM renders the interactive graphic. The circle is styled with a default black fill and no animation or smoothing, providing a direct, immediate link between input and visual output.

Interaction With React, mouse follower

A red circle follows the cursor inside an SVG canvas in this React-based interactive visualization. The example demonstrates a mouse-follower interaction using React's `useState` hook to track pointer coordinates and update the circle's `cx` and `cy` attributes in real time. The `App` component renders an SVG element with an `onMouseMove` event handler, which calls `setMousePosition` on each pointer movement. The circle’s position is bound to the stored mouse coordinates, creating a direct visual response. The code uses React 16.9.0, ReactDOM, and the SVG `circle` element, with the canvas sized at 960 by 500 pixels.

Interaction with React

This example demonstrates a React-based SVG visualization where a circle follows the mouse pointer across a 960-by-500 viewport. It shows how mouse events and unidirectional data flow manage interactive state in React, using the `useState` hook to track cursor coordinates and `useCallback` for the event handler. The single-circle rendering, with a white inner circle, updates its `cx` and `cy` attributes on every `onMouseMove` event, relying on D3 v6 for SVG utilities and React 16 for component rendering.

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 circle follows the mouse cursor within an SVG canvas, updating its position in real time as the pointer moves. Built with React, the application tracks mouse coordinates using an `onMouseMove` event handler and stores them in state via `useState`. The circle’s `cx` and `cy` attributes are bound to this state, and the SVG is rendered through ReactDOM. D3.js is included but not used for drawing; the interaction relies solely on React’s event system.
