Fork of Smiley Face Part II

A React application renders a full-screen SVG that displays a single black-outlined circle following the mouse cursor. The circle’s position updates dynamically via React’s `useState` and `useCallback` hooks, which capture `event.clientX` and `event.clientY` from the SVG’s `onMouseMove` handler. Built with React 16.9 and rendered through `ReactDOM.render`, the visualization uses SVG elements to draw the circle and relies on the browser window dimensions for its initial sizing.

This interactive React and SVG visualization displays a single yellow circle that follows the user's mouse movements across the full browser window. The circle's position is updated through React's `useState` hook, with mouse coordinates captured by the `onMouseMove` event handler on the SVG element. Rendering is handled by ReactDOM, which renders the circle element with dynamic `cx` and `cy` attributes. The code uses the window dimensions to size the SVG canvas, and the circle has a fixed radius of 30 pixels.

This example shows a single unfilled circle that follows the mouse cursor across the full browser window, rendered as an SVG element. The circle’s center coordinates update continuously on mouse movement, using React’s `useState` and `useCallback` hooks to manage and optimize state changes. The visualization is built with React 16.9 and ReactDOM, rendering directly to the DOM, with the SVG’s `onMouseMove` event driving the interactive behavior. The underlying code includes commented-out static smiley-face circles, indicating the fork’s evolution from a fixed illustration to a mouse-tracking interactive graphic.

This example shows a simple interactive visualization where a single circle follows the user's mouse movements across an SVG canvas. The React component tracks the mouse position using the `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` attributes in real time. The code uses React 16.9.0 with `ReactDOM.render` to mount the SVG element, and the initial mouse position is set to the center of the 960×500 viewport.

A React application renders a single SVG circle that follows the mouse cursor as it moves across a 960×500 viewport. The circle’s position updates via React’s `useState` and `useCallback` hooks, which track the cursor’s `clientX` and `clientY` coordinates from the SVG’s `onMouseMove` event. The example demonstrates interactive rendering with React 16.9 and SVG, using a simple state-driven approach to update the circle’s `cx` and `cy` attributes in real time.

A React application renders a single black circle that follows the mouse cursor across the full browser window. The circle repositions dynamically based on the user's pointer movements, updating its coordinates in real time. The implementation uses React's `useState` and `useCallback` hooks to track the mouse position and optimize the event handler, while ReactDOM renders the SVG element with an `onMouseMove` listener. The SVG viewport fills the entire viewport, with the circle radius fixed at 30 pixels.

This interactive React visualization displays a single black circle on a blank SVG canvas that follows the user’s mouse movements. It demonstrates a simple event-driven interaction where the circle’s center coordinates update in real time based on the pointer’s clientX and clientY values. Built with React 16.9, the app uses the useState and useCallback hooks to manage and update the mouse position state, while the SVG onMouseMove handler triggers these updates. The example shows how React’s declarative rendering can create responsive, mouse-tracked graphics in a minimal, frame-free environment.

A circle follows the mouse cursor across an SVG canvas, with its horizontal and vertical position updated in real time to match the pointer’s coordinates. The example demonstrates state management in React, using the `useState` hook to store the cursor position and the `useCallback` hook to handle mousemove events. The `ReactDOM.render` method mounts the component to the DOM, while the SVG’s `onMouseMove` listener triggers updates, with the circle’s center assigned via `cx` and `cy` attributes.
