A single gray circle tracks the mouse cursor as it moves across a blank white SVG canvas. The circle’s center directly follows the pointer position, which is captured and stored in React state on every mouse-move event. This example uses React’s `useState` and `useCallback` hooks, along with `d3.v7` for SVG rendering, to update the circle’s `cx` and `cy` attributes in real time. No data source is involved; the visualization simply demonstrates interactive pointer tracking within a fixed 960×500 viewport.

Mouse

A black circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React's `useState` and `useCallback` hooks to manage and update the circle's coordinates based on `mousemove` events, while D3.js v7 is loaded but not directly used. The visualization shows a minimal interactive pattern, where the circle moves fluidly with cursor movement and renders via React's declarative JSX syntax.

mouse movement

A single black circle tracks the user's mouse position across an SVG canvas, creating a simple interactive visualization. The application is built with React and D3 v7, using React's `useState` hook to store and update the mouse coordinates on every `mousemove` event. The circle's center (`cx` and `cy`) is bound directly to the state, and its radius is fixed at 30 pixels. The rendering is handled entirely through React's declarative SVG elements, with no D3 components used beyond the library's inclusion in the script tags.

Mouse follow

A moving circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The example uses React state management with the `useState` and `useCallback` hooks to track cursor coordinates, and renders the circle via SVG elements in a React component. Mouse move events trigger updates to the circle's center position, initialized to the middle of a 960×500 viewport. The visualization demonstrates a simple interactive pattern using React's declarative rendering and event handling.

Mouse follower

A single gray circle follows the mouse pointer across an SVG canvas. The example uses React state to track the cursor’s clientX and clientY coordinates on every mousemove event, updating the circle’s cx and cy attributes accordingly. Rendered as an SVG circle with a fixed radius, it starts at the center of a 960×500 viewport. The implementation combines React’s useCallback and useState hooks with D3.js v6, though D3 is only loaded and not actively used in the logic.

Mouse Tracking

A single black circle tracks the user's mouse cursor across a blank SVG canvas. The visualization demonstrates how React state updates on every mouse movement event, with the circle's center position re-rendered accordingly. It uses React's `useState` and `useCallback` hooks along with the `onMouseMove` event handler, while D3 v5 is loaded but not directly used in the interaction logic.

Mouse Follower

The example displays a single gray circle that tracks the mouse cursor across an SVG canvas. Mouse movement triggers a React state update, repositioning the circle’s center coordinates. The code uses React’s `useState` and `useCallback` hooks within an SVG `onMouseMove` handler, while D3 v5 is loaded but unused. Rendering is handled by ReactDOM, with a fixed viewport of 960 by 500 pixels and a circle radius of 30.

Mouse Follower

A single gray circle tracks the mouse cursor across an SVG canvas, updating its position in real time. Built with React, the app uses the `useState` hook to store the cursor’s coordinates and a `handleMouseMove` callback triggered by the SVG’s `onMouseMove` event to update them. Rendered without D3 or external data, the circle’s `cx` and `cy` attributes are bound directly to the state values.

Mouse Follower

A single gray circle tracks the mouse’s exact position across an SVG canvas, updating its center coordinates in real time as the pointer moves. Built with React’s `useState` and `useCallback` hooks, the circle’s `cx` and `cy` attributes are re-rendered on every `mousemove` event, using the `clientX` and `clientY` values from the event object. D3 is loaded but only for its `arc` import, which remains unused in the visible code. The SVG viewport is fixed at 960 by 500 pixels.
