A circle follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's pixel coordinates and updates the circle's center position on every mouse move. The code imports the `arc` function from d3 but does not use it; rendering is handled entirely through React's declarative SVG elements. The example demonstrates a simple interactive pattern using React's `useState` and `useCallback` hooks within a D3-styled viewport.

A Program that follows your mouse with a circle

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position in real time. The visualization uses React state to track the cursor's clientX and clientY coordinates, triggered by an onMouseMove event handler on the SVG element. Built with React 16.9 and D3 v7, the circle is rendered directly as an SVG `<circle>` element, with its cx and cy attributes bound to the current mouse position. No data source is involved; the interaction is purely event-driven.

A program that follows your mouse with a circle.

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The code uses React's `useState` hook to track the cursor's client coordinates and re-renders the circle's `cx` and `cy` attributes accordingly. The example imports `range` from d3.v7 and builds an SVG element with a mouse-move event handler that captures the cursor's position. No data visualization occurs; the interaction is purely a demonstration of event handling and state-driven SVG rendering in a React environment.

follow the mouse

A single circle follows the mouse cursor across a 960 by 500 SVG canvas. The example demonstrates interactive SVG rendering in React, updating the circle's `cx` and `cy` attributes on every `MouseMove` event. It uses React’s `useState` hook to store the cursor's client coordinates and re-renders the circle accordingly. The code relies on React 17 and ReactDOM to manage the SVG element, with no D3 functions invoked beyond the imported `arc`, which is unused in the final visualization.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to manage mouse coordinates, with the `onMouseMove` event handler updating the circle's center. D3's `arc` module is imported but not used, while the SVG `<circle>` element is rendered directly through ReactDOM. The visualization demonstrates a simple interactive pattern without any data source or animation logic beyond direct mouse tracking.

Mouse follower

A React application renders an SVG circle that tracks the mouse cursor in real time. The circle's position updates via React's `useState` and `useCallback` hooks, which handle `mousemove` events on the SVG element. The example demonstrates simple interactive rendering with D3's `arc` import unused, relying instead on React's declarative state management. The visualization uses a 960x500 SVG canvas with a fixed circle radius, showing how React can manage dynamic visual updates without explicit D3 selection or transition APIs.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management with a `useState` hook and the `onMouseMove` event handler, which captures the cursor's client coordinates and passes them to the circle's `cx` and `cy` attributes. React re-renders the SVG element on each mouse movement, while D3's `arc` import is present but unused, and no external data source is involved.

Mouse Follower

A black circle follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's position and updates the circle's center coordinates in real time. The code leverages React hooks like `useState` and `useCallback`, with the `arc` function imported from d3, though only a standard `circle` element is rendered. The SVG's `onMouseMove` handler drives the interaction, displaying a simple, responsive pointer-tracking effect.

Mouse follower

A React-controlled SVG circle follows the user's mouse position across a 960×500 canvas, updating its coordinates on every `mousemove` event via the `useState` and `useCallback` hooks. The code imports `arc` from D3 v5 but does not use it, relying instead on React's synthetic event handling and direct SVG attribute updates. The circle’s center is bound to `mousePosition`, with an initial default at the canvas midpoint, and the page hides browser scrolling for a focused interactive demonstration.
