A circle follows the mouse as it moves over an SVG canvas. The visualization tracks the cursor’s client coordinates and updates the circle’s center position in real time. Built with React hooks (`useState` and `useCallback`), it handles mouse movement via the SVG `onMouseMove` event, re-rendering the circle’s `cx` and `cy` attributes. The example uses React 16.9 and ReactDOM for rendering, with a static SVG viewport of 960 by 500 pixels.

dv.14 - Mouse Follewer

A full-screen SVG circle follows the mouse cursor in real time, remaining centered on the current pointer position. The example uses React with the `useState` and `useCallback` hooks to track cursor coordinates and update the circle's `cx` and `cy` attributes. React DOM renders the SVG element, which listens for `onMouseMove` events, and the circle's radius is fixed at 30 pixels. The visualization demonstrates a simple interactive pointer-tracking effect with no external data source.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas. The visualization demonstrates real-time interaction by updating the circle's center coordinates to match the pointer’s position. Built with React 16.9, it uses the `useState` hook to track mouse coordinates and the `onMouseMove` event handler on the SVG element. The rendering is handled entirely through SVG, with the circle’s `cx` and `cy` attributes updated on every mouse movement.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas in this React-based visualization. The app tracks pointer coordinates using a React `onMouseMove` event handler and stores them in component state with the `useState` hook. Each mouse movement updates the circle’s `cx` and `cy` attributes, repositioning it instantly at the cursor’s location. The visualization uses React 16.9 and D3 v5 for rendering, with the SVG circle set to a fixed radius of 30 pixels. No data source is involved; the interaction is purely driven by user input.

follow the mouse

A single circle follows the mouse cursor across a 960 by 500 SVG canvas. The example demonstrates interactive SVG rendering in React, updating the circle's `cx` and `cy` attributes on every `MouseMove` event. It uses React’s `useState` hook to store the cursor's client coordinates and re-renders the circle accordingly. The code relies on React 17 and ReactDOM to manage the SVG element, with no D3 functions invoked beyond the imported `arc`, which is unused in the final visualization.

Mouse follower

A circle follows the cursor as it moves across an SVG canvas. The example uses React’s `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. The SVG’s width is fixed at 960 pixels and height at 500, with the initial position centered. The rendering is done entirely through React’s declarative component structure, producing a simple interactive visualization without any external data sources.

Mouse follower

A circle follows the mouse cursor across a full-window SVG canvas, reacting in real time to pointer movement. The React component tracks mouse coordinates via the `onMouseMove` event, updating state with `useState` and `useCallback`, then re-renders the circle’s `cx` and `cy` attributes. The visualization uses React 16.9 and ReactDOM to render SVG elements directly in the browser.

Mouse Follower

An interactive SVG visualization renders a single circle that follows the mouse cursor across a 960-by-500 canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Initially positioned at the canvas center, the circle moves smoothly with the cursor. The example demonstrates state-driven rendering in React 17 with D3 v7, using plain SVG elements rather than data joins or scales. No external data source is involved; the visualization purely reacts to user input.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time based on pointer movement. The visualization demonstrates mouse-event handling and state-driven rendering with React, using the `useState` hook to store the cursor coordinates and `onMouseMove` to update them. ReactDOM renders an SVG circle whose `cx` and `cy` attributes are bound to the tracked position, with the viewport dimensions fixed at 960 by 500 pixels. No data source or external computation is involved; the example relies solely on React's declarative update cycle.
