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.

Fork of Smiley Face Part III

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 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.

This example renders a minimal smiley face in an SVG canvas using React and D3. The visualization displays a single yellow circle with black outlines for the face and eyes, positioned at coordinates derived from the window dimensions. The implementation relies on React’s declarative components and D3’s `arc` API, though the current code only draws the face outline and eyes without additional interactivity. A mouse-move handler is defined but only logs events to the console. The SVG output is generated statically via React’s `ReactDOM.render` into a DOM root element.

A mouse-driven smiley face follows the cursor across an SVG canvas. The face is a single orange circle rendered with React state tracking the mouse position. The code uses React hooks `useState` and `useCallback` to update the circle's `cx` and `cy` attributes on every `mousemove`. D3's `arc` function is imported but unused in this implementation. The example demonstrates simple React-D3 integration with direct SVG rendering.

The example shows a small smiley face rendered as an SVG that follows the mouse cursor across a 960-by-500 canvas. The face’s position is driven by React state, updated via an `onMouseMove` handler that records the client coordinates. D3’s `arc` generator defines the mouth path, while circles for the face, eyes, and stroke are drawn using React’s JSX syntax. The visualization combines React’s declarative component model with D3’s geometry utilities, using `d3.v5` and `react@16.9.0`.

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 React and D3 interactive visualization displays a single circle that follows the mouse cursor across an SVG canvas. The code uses React's `useState` and `useCallback` hooks to track mouse coordinates, updating the circle's `cx` and `cy` attributes on every `mousemove` event. Rendered with React's `ReactDOM.render` into an SVG element, the example demonstrates how D3's SVG capabilities can be integrated with React state management for real-time user interaction.

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.
