A red circle follows the mouse in an inverted, mirrored motion across a full-window SVG canvas, growing in radius as the cursor moves horizontally. It uses an SVG `circle` element bound to `mousemove` events on the root `<svg>` via D3 v7's `select` and `attr` methods. The circle's `cx` and `cy` coordinates are set to negative mouse positions offset by 400, while its `r` scales with `event.x`, with `fill` hardcoded to red.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas, with its position updating in real time. Built with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates on a dedicated SVG `onMouseMove` event handler. ReactDOM renders the SVG, and the circle's `cx` and `cy` attributes update live as the pointer moves.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves. Built with React and D3 v5, the app uses React’s `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle’s `cx` and `cy` attributes accordingly. No data source is involved; the visualization simply demonstrates interactive event handling and state-driven rendering with SVG.

A circle follows the mouse cursor across a 960 by 500 pixel SVG canvas, updating its position in real time as the pointer moves. The visualization is built with React (using the `useState` hook) and renders the circle via an SVG `<circle>` element. Mouse movement is captured through the SVG's `onMouseMove` event handler, which updates the circle's `cx` and `cy` coordinates. The example uses D3.js v7 and ReactDOM to render directly into the page's root element, with no external data source.

A red circle follows the mouse cursor across a full-screen SVG canvas, with its center position updating in real time to match the pointer coordinates. The visualization uses React hooks (useState and useCallback) to manage the cursor position state and handle mouse movement events. The circle’s coordinates are bound directly to the mouse event’s clientX and clientY values, and the SVG viewport spans the entire browser window.

Mouse Follower

An interactive SVG circle follows the mouse cursor across a 960x500 canvas. The React application tracks pointer movement via the `onMouseMove` event handler, updating the circle's center coordinates with each `clientX` and `clientY` value. Using `useState` for position state and `useCallback` to optimize the event handler, the code renders a single red circle (radius 30) whose position updates in real time. The example demonstrates a basic React-D3 integration, with the visualization rendered entirely through React's declarative SVG output.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example uses React with a `useState` hook to track the mouse position, updating the circle's `cx` and `cy` attributes during `onMouseMove` events. It renders a single red circle with a radius of 30 pixels inside an SVG viewport sized 960 by 500 pixels, using D3.js version 7 and React 18.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas. The visualization updates the circle’s position in real time using React state and event handling, triggered by `onMouseMove`. It renders with SVG elements in a React component, using the `useState` and `useCallback` hooks to manage position updates. The code imports the `arc` function from d3, though the current implementation only uses a basic circle element.

Mouse Follower

A black circle follows the mouse cursor across a yellow SVG canvas, responding instantly to every pointer movement. The visualization uses React's `useState` hook to track the current mouse coordinates and updates the circle's `cx` and `cy` attributes on each `mousemove` event. The root SVG element captures mouse movements via React's `onMouseMove` handler, and the circle is rendered with a fixed radius and black fill, creating a simple, direct interaction between the user and the graphic.
