This example demonstrates a smiley face that follows the mouse cursor across an SVG canvas. As the user moves their pointer, a yellow circle with a black outline tracks the cursor’s exact position in real time. The visualization is built using React’s `useState` and `useCallback` hooks to manage and update the mouse coordinates, with the `onMouseMove` event handler updating the state. D3’s `arc` function is imported but unused, while ReactDOM renders the SVG circle whose `cx` and `cy` attributes are bound to the tracked position, creating a responsive interactive effect.

Mouse move

A single black circle follows the user’s mouse movement across an SVG canvas. The circle’s center position updates in real time, tracking the cursor’s clientX and clientY coordinates. The example uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while D3’s `arc` is imported but not used in the visible code. The SVG renders within a React component, with a yellow static smiley face shown only as a commented-out reference in the HTML.

Mouse Follower

A smiley face follows the mouse cursor across an SVG canvas, demonstrating how React state updates can drive dynamic D3 visualizations. The example uses React's `useState` and `useCallback` hooks to track mouse coordinates, which are captured via an `onMouseMove` event handler on the SVG element. A single yellow circle with a black stroke and two smaller eye circles are rendered, with the main circle's position updating in real-time to match the cursor. The code leverages d3.v7 for SVG utilities and React 16.9 for component-based rendering.

Mouse follower

This example shows a simple smiley face that follows the mouse cursor across a 960-by-500 SVG canvas. The face is drawn with a yellow linear gradient, two elliptical eyes, and a d3.arc-generated mouth, all assembled from React components. As the user moves the mouse, the React state updates the circle’s center coordinates via the `onMouseMove` handler, re-rendering the face at the new position. The code uses React’s `useState` and `useCallback` hooks, along with d3’s `arc` for the mouth path, and renders everything as SVG elements.

MouseMover Smiley Face

This example demonstrates a single, small circle that follows the mouse cursor across an SVG canvas. Built with React, it uses the `useState` hook to store the cursor’s client coordinates and the `useCallback` hook to define the `onMouseMove` event handler, which updates those coordinates on every mouse movement. The view renders a yellow smiley face (a face with eyes and a mouth) as a static SVG background, while the movable circle acts as an interactive pointer. The code relies on React’s `ReactDOM.render` to mount the component into the page’s root element.

MouseMoveEvent

A smiley face circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves the pointer. The React component tracks mouse coordinates through an `onMouseMove` event handler, storing them in state via `React.useState` and updating the circle's `cx` and `cy` attributes. The visualization uses React 18, D3 v7 for the SVG rendering, and demonstrates simple interactive event handling without any external data source.

mouse follower

A yellow smiley face follows the mouse cursor across an SVG canvas. The face’s components—eyes, brows, and an arc-shaped mouth—are built with React state and D3’s `arc` generator, repositioned via a `transform` attribute on each mouse move. The example uses `useState` and `useCallback` to track cursor coordinates, and ReactDOM renders the interactive graphic.

Mouse Follower

A smiley face follows the mouse cursor across an SVG canvas, its position updating in real time with every pointer movement. The example combines React 16.9's `useState` and `useCallback` hooks to manage the circle's `cx` and `cy` attributes, while D3 v5 supplies the `arc` import. Rendering is handled through ReactDOM's `render` method, which places an interactive `<svg>` with an `onMouseMove` listener into the page root.

Mouse Follower

A smiley face follows the mouse cursor across a full-screen SVG canvas. The application tracks the pointer's position and renders a yellow circle with facial features at that location, creating a playful interactive effect. Built with React and ReactDOM, the example uses the `onMouseMove` event handler and `useState` to update the circle's `cx` and `cy` coordinates dynamically. The SVG viewport matches the browser window dimensions, and the smiley face’s position updates instantly as the user moves the mouse.
