A yellow smiley face follows the mouse cursor across an SVG canvas, with its circular head and facial features drawn in React and D3. The face tracks pointer movement via React state and an `onMouseMove` event, while D3’s `arc` function defines the smile shape. The implementation uses reusable SVG circle elements, fixed dimensions of 960 by 500 pixels, and a 20-pixel stroke for the head outline. The example demonstrates integrating React’s component state with D3’s geometry utilities for interactive visualization.

A smiley face rendered as SVG responds to mouse movement, with a circle tracking the cursor across a screen-sized canvas. Eight yellow rectangles with black borders form the face’s background pattern, while the moving circle serves as a dynamic feature. The code combines React state management via `useState` and `useCallback` with D3 v5, using `Array.from` to generate the rectangles and inline SVG elements for rendering. React handles updates on `onMouseMove`, while D3 is imported but not directly used for drawing.

A smiley face rendered as an SVG follows the mouse cursor across a 960×500 canvas. The example combines React for state management with D3.js for SVG generation, using a `circle` element whose `cx` and `cy` coordinates update via a `mouseMove` event handler. The React `useState` hook tracks the cursor position, and `useCallback` optimizes the event handler. Though the code defines a yellow face with black outline and two eye circles in an HTML comment, the interactive version displays only a single moving circle, driven by `ReactDOM.render` and D3 v5.

A yellow smiley face rendered with React and D3 follows the mouse cursor across the screen. The face uses D3’s `arc` generator to draw the mouth, while the eyes are separate circles whose red pupils shift position based on the cursor’s coordinates. Mouse movement updates React state via a `mousemove` listener, triggering re-renders of the SVG elements. The visualization is built with React 16.9, D3 v7, and SVG, with hardcoded dimensions of 960 by 500 pixels.

A yellow smiley face is rendered as an SVG graphic, centered within a 960 by 500 viewport. The face consists of three circles for the head and eyes, and an arc for the mouth, all drawn using React components and the D3 `arc` function. The React code constructs the SVG elements dynamically, with D3’s `arc` generator computing the mouth’s path based on specified inner and outer radii and angles. The example demonstrates combining React’s declarative UI with D3’s geometric utilities.

A simple SVG smiley face rendered with React and D3. The face consists of a yellow circle, two eye circles, and a mouth drawn as an arc path using `d3.arc()` with defined inner and outer radii and start/end angles. React manages the SVG elements declaratively, while D3 computes the mouth’s path geometry. All shapes are positioned relative to a central transform group. The code runs in a browser using React 16.9, ReactDOM, and D3 v5, with coordinates and dimensions specified as constants.

A smiley face is drawn as a yellow circle with black outline and two eyes, rendered as SVG elements within a React component. The visualization tracks the mouse position across the screen, dynamically updating the location of a separate red circle that follows the cursor using React state and event handling. The code uses React hooks like `useState` and `useCallback`, along with inline event handlers, to manage the interactive behavior. The rendering is done with D3 v6 and React in an SVG container that fills the entire window.

A smiley face icon follows the user's cursor across an SVG canvas, updating its position in real time as the mouse moves. Built with React and D3 v5, the example uses React's `useState` and `useCallback` hooks to track mouse coordinates and trigger re-renders. The `onMouseMove` handler on the SVG element captures client coordinates, which are then passed to a circle element's `cx` and `cy` attributes to reposition the face.
