A black dot follows the mouse cursor across an SVG canvas. The application is built with React, using the `useState` hook to store the cursor's `clientX` and `clientY` coordinates and `useCallback` to prevent unnecessary re-renders during mouse movement. The `onMouseMove` event triggers updates to a circle element's `cx` and `cy` properties, with radius fixed at 30 pixels. The chart uses D3's `arc` import and renders via the `ReactDOM.render` method against a background of 960 by 500 pixels.

AI-generated description

It is a mouse following black dot. Some important notes on useState and useCallback.Btw event has 2 properties namely clientX and clientY which gives us the coordinates of x and y.

Mouse Follower

A black circle follows the mouse cursor within an SVG canvas. The circle’s position updates in real-time based on the pointer’s coordinates, creating a direct and responsive visual link between user input and the rendered graphic. This interaction is built with React using the `useState` hook to track mouse position, which is updated via an `onMouseMove` event handler on the SVG element. The chart is rendered as SVG, leveraging the `d3` library’s `arc` import, though it primarily relies on React’s state management for the dynamic behavior.

mouse follower

A mouse follower demonstrates a simple interactive visualization using React and D3. A single black circle tracks the user's cursor as it moves across an SVG canvas, updating its position in real time. The application uses React's `useState` and `useCallback` hooks to manage the mouse coordinates, while the `onMouseMove` event handler captures the clientX and clientY values. D3 v5 is loaded but only used for its `arc` import, which is not actually called in the visible code. The SVG rendering approach is handled entirely through React's JSX syntax.

Mouse Follower

A circle follows the mouse cursor across a 960-by-500 SVG canvas, updating its center position in real time. Built with React using the `useState` and `useCallback` hooks, the app listens for `onMouseMove` events on the SVG element and passes the cursor's `clientX`/`clientY` coordinates to the circle's `cx` and `cy` attributes. The visualization uses D3.js version 5 primarily for the SVG rendering within a React framework, with no external data source.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas in this React-based visualization. The app tracks pointer coordinates using a React `onMouseMove` event handler and stores them in component state with the `useState` hook. Each mouse movement updates the circle’s `cx` and `cy` attributes, repositioning it instantly at the cursor’s location. The visualization uses React 16.9 and D3 v5 for rendering, with the SVG circle set to a fixed radius of 30 pixels. No data source is involved; the interaction is purely driven by user input.

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 follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's position and updates the circle's center coordinates in real time. The code leverages React hooks like `useState` and `useCallback`, with the `arc` function imported from d3, though only a standard `circle` element is rendered. The SVG's `onMouseMove` handler drives the interaction, displaying a simple, responsive pointer-tracking effect.

Mouse Follower

A black circle of radius 30 follows the mouse cursor across a 960-by-500 SVG canvas. React's `useState` and `useCallback` hooks track the cursor’s client coordinates, updating the circle’s `cx` and `cy` attributes on every `mousemove` event. D3 v5 is loaded but not used in the visible logic; rendering is purely React-driven SVG.

A single black circle follows the mouse cursor across an SVG canvas. The circle’s position updates on every `mousemove` event, driven by React state. The application uses React’s `useState` and `useCallback` hooks to track the cursor’s coordinates and re-render the circle accordingly. The example is rendered with D3.js v6 for SVG creation, while React handles the interactive state, with no external data source.
