This example demonstrates a real-time interactive visualization where a circular SVG element follows the mouse cursor across a 960x500 canvas. Built with React 17 and D3 v7, the application uses React’s `useState` and `useCallback` hooks to track mouse coordinates through an `onMouseMove` event handler on the `<svg>` element. As the pointer moves, React re-renders the circle’s `cx` and `cy` attributes, updating its position instantly. The visualization highlights how React manages state-driven updates for DOM elements, contrasting with D3’s imperative approach to data binding.

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 circle follows the mouse cursor within an SVG canvas, demonstrating interactive state updates in React. The app tracks mouse movement via the `onMouseMove` event handler on the `<svg>` element and updates the circle’s `cx` and `cy` attributes using React’s `useState` hook. The visualization combines React 17 with D3 v7 for rendering, using a simple SVG `<circle>` element with a fixed radius. The code explicitly manages the circle’s position in React state rather than using D3’s data-binding, highlighting the interaction between React’s declarative model and SVG.

interaction with react

A circle follows the mouse pointer inside an SVG canvas, with its center position updating in real time. The example demonstrates how to combine React's state management with event handling for interactive visualizations. The code uses React's `useState` hook and `useCallback` to track mouse coordinates, while D3.v5 provides the SVG rendering environment. The circle's `cx` and `cy` attributes update dynamically based on the mouse movement events captured by the SVG's `onMouseMove` handler.

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

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 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

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.

Building Interactivity with React

An interactive SVG circle follows the mouse as it moves across the screen, demonstrating how React manages state and event handling for dynamic visual updates. Built with React 17 and D3 v7, the component uses `useState` and `useCallback` to track the cursor position and update the circle's `cx` and `cy` attributes on every `mousemove`. The rendered output is a single yellow circle on a blank canvas, showcasing the integration of React's declarative JSX syntax with SVG elements inside a simple, resizable viewport.
