A circle follows the mouse cursor across an SVG canvas, updating its position in real time in response to pointer movement. The React state hook `useState` stores the current mouse coordinates, while the `onMouseMove` event handler updates that state through `setMousePosition`. The `useCallback` hook optimizes the event handler, and ReactDOM renders the component to the page. This example demonstrates how React manages interactive SVG rendering without any external data source or D3 dependency.

Interaction with React

A circle in an SVG canvas follows the mouse cursor, with its position updated continuously. The example demonstrates unidirectional data flow in React, where the current mouse coordinates serve as state and drive the circle's rendering. It uses React's `useState` and `useCallback` hooks to manage the mouse position and optimize event handling. The SVG element listens for mouse movement events, and the circle's `cx` and `cy` attributes are bound to the state values, rendering via ReactDOM with an inline SVG.

Interaction with React

A circle follows the cursor as it moves across an SVG canvas. The example demonstrates how React manages interactive state for a simple visualization, using the `useState` and `useCallback` hooks to track mouse coordinates and update the circle's position. React 16.9 renders the SVG element, which listens for `onMouseMove` events and updates the `cx` and `cy` attributes of the circle in real time.

Mouse Follower

This example demonstrates how React state can drive an interactive SVG visualization: a single circle follows the mouse cursor across a 960x500 viewport. On every mousemove event on the SVG, the `handleMouseMove` callback updates the `mousePosition` state with the cursor’s client coordinates, and React re-renders the circle’s `cx` and `cy` attributes accordingly. It uses React 16.9 with hooks (`useState`, `useCallback`) and renders directly to SVG via `ReactDOM.render`.

Interaction with React: Mouse follower

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 across an SVG canvas, updating its position in real-time in response to mouse movement. The example demonstrates state management in React, using the `useState` hook to store mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event. The circle is rendered as an SVG `<circle>` element within a React component, with the width and height set to 960 and 500 pixels. The visualization uses React's declarative rendering to update the circle's `cx` and `cy` attributes as the mouse moves.

Interaction with React

An interactive SVG circle follows the mouse cursor across a 960 by 500 canvas, updating its position in real time. Built with React, the component uses the `useState` hook to track mouse coordinates and a `useCallback` event handler for the `onMouseMove` SVG attribute. The circle’s center point and radius are explicitly set within the rendered SVG, demonstrating state-driven updates without a separate data source.

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.

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.
