This example demonstrates a mouse-follower visualization: a circle that tracks the cursor’s position across an SVG canvas. The circle moves continuously as the user moves the mouse, with its center coordinates updated from the event’s `clientX` and `clientY` values. The implementation uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while the `<svg>` element’s `onMouseMove` handler triggers the state change. The rendering is done via SVG, with a single `<circle>` element whose `cx` and `cy` attributes are bound to the current position. D3 is loaded but not used for interaction or data processing.

Mouse follower

This example shows a circle that follows the mouse cursor across an SVG canvas. It demonstrates React state management with the `useState` and `useCallback` hooks, where mouse coordinates from the `onMouseMove` event update the circle’s position. The visualization renders with React DOM into an SVG element using d3.v7, with the initial circle centered at the viewport midpoint.

Mouse Follower

This example shows a single circle that continuously tracks the user’s cursor within an SVG canvas, centering itself on the mouse’s current coordinates. The visualization relies on React’s `useState` and `useCallback` to capture `clientX` and `clientY` from the SVG’s `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. Initially positioned at the canvas center, the circle reacts instantly to any pointer movement, demonstrating a minimal interactive pattern with no external data source.

Mouse Follower

A simple interactive visualization renders a single circle that follows the mouse cursor across an SVG canvas. The circle’s position updates in real time, tracking the user's pointer movement. The example uses React’s `useState` and `useCallback` to manage the mouse coordinates, and renders the circle via an SVG `<circle>` element with `cx` and `cy` attributes set from the current mouse position. The `onMouseMove` event handler on the SVG element captures the cursor's `clientX` and `clientY` values, which are then used to update the circle’s location.

Mouse follower

A circle tracks the mouse cursor across an SVG canvas, reacting instantly to movement. The visualization demonstrates state management in React, using the `useState` hook to store cursor coordinates and `useCallback` to optimize the mouse-move handler. The SVG circle updates its `cx` and `cy` attributes based on those coordinates, rendered via ReactDOM. The example uses D3.js v7 only for its bundled build, while the core interaction is purely React-driven.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React state to track mouse coordinates via the `onMouseMove` event handler and renders a single `<circle>` element with D3 v7’s selection-free React integration. The SVG viewport is fixed at 960 by 500 pixels, and the circle’s center tracks the clientX and clientY values directly.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The visualization demonstrates React's state management with D3's event handling, using a `useState` hook to track cursor coordinates and a `useCallback` hook to efficiently update the circle's `cx` and `cy` attributes on every mouse move. The D3 v5 library renders the SVG element.

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.
