A black circle follows the mouse as it moves across an SVG canvas. The example demonstrates how to use React state to track cursor position and update a visualization in response to user interaction. The `App` component uses React's `useState` hook to store the circle's coordinates, and the `onMouseMove` event on the `<svg>` element updates that state with `event.clientX` and `event.clientY`. The circle is rendered as an SVG `<circle>` element with its `cx` and `cy` attributes bound to the state values.

mouse follower

A single black circle on an SVG canvas tracks the user's mouse cursor in real time, creating a simple interactive visual. The example demonstrates state management in React, using the `useState` and `useCallback` hooks to update the circle's `cx` and `cy` attributes on every `mousemove` event. Rendered with SVG elements, the circle is positioned via React's `onMouseMove` handler, while D3 v5 and React 16 are loaded externally. No data source is involved; the visualization purely reacts to pointer movement within the 960 by 500 pixel viewport.

Mouse Follower

A black circle on a white background follows the mouse cursor across an SVG canvas. The example illustrates React state management and event handling by updating the circle's center coordinates in response to every mouse move. The `App` component uses React's `useState` hook to track the cursor position and `useCallback` to define the move handler. React renders the SVG element, updating the `cx` and `cy` attributes reactively.

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 Follower

A black circle follows the mouse as it moves across a blank 960×500 SVG canvas. The example shows how React state updates, triggered by mouse events, can drive SVG attribute changes in real time. The React component `App` uses the `useState` hook to store the pointer’s `clientX` and `clientY` coordinates, updating them via a `handleMouseMove` callback on the `<svg>` element’s `onMouseMove` event. The circle’s `cx` and `cy` properties are bound directly to this state, rendering with d3.v7 and ReactDOM.

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 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.

Interaction with react

A circle follows the mouse cursor within an SVG canvas, demonstrating interactive state updates in React. The app tracks mouse movement via the `onMouseMove` event handler on the `<svg>` element and updates the circle’s `cx` and `cy` attributes using React’s `useState` hook. The visualization combines React 17 with D3 v7 for rendering, using a simple SVG `<circle>` element with a fixed radius. The code explicitly manages the circle’s position in React state rather than using D3’s data-binding, highlighting the interaction between React’s declarative model and SVG.

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.
