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.

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.

Interaction With React

A React application demonstrates mouse interaction by rendering a single circle that follows the cursor across an SVG canvas. The code uses React’s `useState` and `useCallback` hooks to track the pointer position and update the circle’s `cx` and `cy` attributes on every `mousemove` event. The circle is drawn with SVG elements, and ReactDOM renders the component into the `#root` div. No external data is loaded; the visualization simply shows real-time positional state changes.

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

This example demonstrates how React manages interactive SVG rendering by drawing a single circle that follows the mouse cursor across the full browser window. The visualization tracks pointer movement through React state and event handling, updating the circle’s position in real time using the `useState` and `useCallback` hooks. The code renders an SVG element with ReactDOM, binding `onMouseMove` to update coordinate values, while the circle’s `cx` and `cy` attributes reflect the current mouse position. No external data source is used; it focuses purely on React’s declarative interaction model.

Interaction with React

A React application renders a single circle that tracks the mouse cursor across an SVG canvas. The component uses the `useState` hook to store the cursor's coordinates and updates them through the `onMouseMove` event handler. Each mousemove event triggers `setMousePosition`, causing React to re-render the SVG circle at the new `clientX` and `clientY` positions. The example demonstrates state-driven updates within a React component, using ReactDOM to mount the app and SVG elements for drawing.

Interaction with React

This example shows a single circle that follows the mouse cursor across the full browser window, demonstrating real-time interaction in a React-based SVG visualization. The circle’s position updates continuously as the user moves the mouse, driven by React’s `useState` and `useCallback` hooks to store and update the cursor coordinates. It uses ReactDOM to render an SVG `<circle>` element, with `onMouseMove` handling events on the SVG root, and the initial mouse position set to the center of the viewport.

Interaction with React (Mouse Follower)

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.
