An interactive visualization renders a single circle that tracks the mouse cursor in real time. The React application uses the `useState` hook to store the cursor’s `clientX` and `clientY` coordinates, updating each mouse move. An SVG circle’s `cx` and `cy` attributes are bound to these state values, producing a smooth follower effect. The example demonstrates combining React’s event handling with D3’s SVG manipulation capabilities for a simple, direct user interface.

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

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

This interactive visualization displays a single circle that follows the cursor as it moves across an SVG canvas. The React application tracks mouse coordinates via an event handler and updates the circle's position accordingly. Built with React and D3.js version 7, the code uses React's state management and callback functions to handle mouse movement events. The rendering is done through an SVG element with a fixed width of 960 pixels and height of 500 pixels, where the circle's center point is repositioned based on the clientX and clientY values from each mouse event.

Mouse Follower

A React application uses an SVG circle to track the mouse cursor across a 960 by 500 coordinate space, with the circle centered initially at the midpoint. The code leverages React's `useState` and `useCallback` hooks to manage and update the cursor position on `mousemove` events. The circle’s position is bound to the mouse coordinates via JSX attributes, rendering a simple interactive visualization that demonstrates real-time state updates in a React-based SVG environment.

Mouse Follower

This interactive visualization displays a single circle that follows the mouse cursor across an SVG canvas. Built with React, the example uses the `useState` hook to track the cursor's `clientX` and `clientY` coordinates within an `onMouseMove` event handler on the `<svg>` element. The circle's center position updates reactively via `setMousePosition`, rendering in real time as the user moves the mouse. The visualization demonstrates a simple, responsive interaction pattern using React's declarative state management and SVG rendering.

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

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.
