A circle follows the mouse cursor across an SVG canvas, its position updating in real time as the pointer moves. Built with React 17, the app uses the `useState` hook to store mouse coordinates and the `useCallback` hook to define the `onMouseMove` event handler. The circle is rendered as an SVG element within a fixed 960×500 viewport, with its `cx` and `cy` attributes bound directly to the state.

Ep14 Interaction with React

This example shows a single circle rendered in SVG that follows the mouse cursor across a 960 by 500 canvas. The circle’s position updates in real time based on the pointer’s client coordinates. Built with React, it uses the `useState` and `useCallback` hooks to manage and update the mouse position state. The `onMouseMove` event handler on the SVG element triggers the state change, and ReactDOM renders the circle element with dynamic `cx` and `cy` attributes.

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

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

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, 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 (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.

Interaction With React

A React application renders an SVG circle that follows the mouse cursor across a 960 by 500 canvas. The component tracks pointer movement via the `onMouseMove` event and updates its state with the current client coordinates. React 16.9 manages the circle's position through the `useState` and `useCallback` hooks, re-rendering the SVG element as the pointer moves. The example demonstrates state-driven interactivity without a data source, relying solely on user input to drive the visualization.

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.
