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

A yellow smiley face follows the mouse cursor across a full-screen SVG canvas, with its eyes and mouth repositioning relative to the cursor's coordinates. The example demonstrates interactive state management in React, using the `useState` and `useCallback` hooks to track `clientX` and `clientY` values from the SVG's `onMouseMove` event. Every mouse movement triggers a state update that re-renders the positioned circles, creating a direct mapping between pointer location and graphical elements. The implementation uses React 16.9 with ReactDOM rendering the SVG output.

Mouse Follower

A smiley face follows the mouse cursor across an SVG canvas, with its position updating in real time. The visualization uses React state and the `useState` and `useCallback` hooks to track mouse coordinates, which are passed to an SVG `<circle>` element’s `cx` and `cy` attributes. The `onMouseMove` event handler on the `<svg>` element triggers the state update, while ReactDOM renders the component. No D3 APIs are used; the example relies purely on React’s declarative rendering with SVG.

A cursor-following smiley face tracks the mouse across an SVG canvas in this React application. The code uses React's `useState` hook to store mouse coordinates and a `useCallback` handler to update them on `onMouseMove` events. Each mouse movement re-renders a single yellow circle with black stroke, whose center position is bound to the current mouse coordinates. The example demonstrates real-time interaction between browser pointer events and declarative SVG rendering through React's state management.

Mouse Follower

A React-based smiley face follows the mouse cursor across an SVG canvas. The example demonstrates interactive state management with React's `useState` and `useCallback` hooks, responding to `onMouseMove` events to update circle coordinates. The rendering uses SVG elements composed with ReactDOM, creating a minimal interactive visualization where a single circle tracks pointer movement within a 960x500 viewport.

A smiley face follows the mouse cursor across the screen, rendered as SVG circles on a hidden-background canvas. Using React hooks (`useState`, `useCallback`) for state management and D3 v5 for event handling, the component tracks pointer coordinates and updates the face’s position accordingly. D3’s mouse interaction API reads the cursor location relative to the container, while React’s state-driven re-rendering animates the yellow circle face, eyes, and smile in real time.

Mouse Follower

A yellow smiley face follows the mouse cursor across an SVG canvas, redrawing its position on every mouse movement event. The face is built from reusable React components—a yellow circle background, two black eye circles, and a mouth drawn with `d3.arc()`—all composed within a `<g>` transform. React state tracks the cursor’s `clientX` and `clientY` coordinates, triggering re-renders via `useState` and `useCallback`. A dropdown menu is present but not connected to the visualization.

Mouse follower

A yellow smiley face follows the user's mouse cursor across a full-screen interactive SVG canvas. The face is drawn with React components that update its position based on mouse movement state. The example uses React 16.9's `useState` and `useCallback` hooks to track cursor coordinates and re-render the SVG circle elements accordingly. All rendering is client-side in the browser with no external data source.

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.
