A React component renders an SVG circle that tracks the mouse position across the full viewport. The circle’s center coordinates update via React state, with the `onMouseMove` event handler feeding client coordinates into a `useState` hook. D3 v5 provides the `arc` import, though the visible geometry relies on plain SVG circle elements. The example demonstrates bidirectional integration of D3’s ecosystem with React’s declarative state management, using the `useCallback` hook to optimize event handling. No data source is involved; the visualization is purely interactive, responding to user input 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 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

A React component renders an SVG circle that follows the mouse cursor across a 960 by 500 viewport. The `App` component uses the `useState` and `useCallback` hooks to track and update the mouse position, binding an `onMouseMove` event handler to the SVG element. This example demonstrates integrating React's state management with D3 v5 and SVG rendering, showing how direct event handling replaces D3's typical selection and data-join pattern.

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

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

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 - Mouse move

A React application renders a single SVG circle that tracks mouse movements across the viewport. As the pointer moves, the circle's center repositions to match the cursor's clientX and clientY coordinates, which are captured by an onMouseMove event handler. The state is managed through React's useState and useCallback hooks, while the SVG coordinate system is defined with explicit width and height attributes of 960 and 500 pixels respectively. The visualization uses d3 v7 and React 18, though it does not rely on D3 for the interaction logic itself.

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.
