A React component tracks the mouse position over an SVG canvas and renders a black circle that follows the cursor. The circle’s center coordinates are updated through React’s `useState` hook and a `handleMouseMove` callback triggered by the SVG’s `onMouseMove` event. The code uses D3 v7 for SVG rendering within a React 17 application, with the circle’s radius fixed at 30 pixels and the initial position set to the center of a 960×500 viewport.

Mouse mover

A circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via an SVG `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes through state. D3’s `arc` import is unused here; rendering relies on React’s `useState` and `useCallback` hooks with a plain `<circle>` element. The visualization demonstrates real-time event-driven SVG updates in a React-D3 hybrid setup.

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

A single black circle follows the mouse cursor across an SVG canvas, with its position updating reactively in real time. The circle’s center is driven by the `clientX` and `clientY` coordinates from the SVG element’s `onMouseMove` event, stored in React state via `useState` and `useCallback`. The visualization uses React 17 for rendering, D3 v7 for SVG utilities, and demonstrates a simple interactive pattern without any data source or external dataset. The circle radius is fixed at 30 pixels, and the SVG viewport is 960 by 500 pixels.

Mouse move

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 Move React

A React SVG visualization tracks the mouse position within a 960 by 500 viewport. It renders a single circle that follows the cursor, using React’s `useState` to store coordinates and `useCallback` to optimize the mouse-move handler. The circle’s center updates directly from the event’s `clientX` and `clientY` values, demonstrating a minimal interactive component built with React 16 and rendered through `ReactDOM.render`.

Mouse event

A React and SVG visualization demonstrates mouse tracking by rendering a single circle that follows the cursor. The circle's position updates dynamically via React's `useState` hook, which stores the mouse coordinates from the `onMouseMove` event handler. The initial position is set to the center of a 960x500 SVG canvas, and the circle has a radius of 30 pixels. The code uses ReactDOM to render the component to the DOM, with the SVG's width and height explicitly defined.

Mouse move

A single black circle follows the user’s mouse movement across an SVG canvas. The circle’s center position updates in real time, tracking the cursor’s clientX and clientY coordinates. The example uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while D3’s `arc` is imported but not used in the visible code. The SVG renders within a React component, with a yellow static smiley face shown only as a commented-out reference in the HTML.
