A React application renders a single circle that tracks the mouse pointer within an SVG canvas. The circle’s center coordinates are updated on every mouse move event using React’s `useState` and `useCallback` hooks, with the `cx` and `cy` attributes bound to the pointer’s clientX and clientY values. The SVG viewport is fixed at 960 by 500 pixels, and the circle has a radius of 60. The example demonstrates real-time, state-driven interaction between mouse events and SVG elements in a React component.

Mouse follower

A React component renders an SVG circle that follows the mouse pointer across a 960×500 viewport. On every mouse move, the `onMouseMove` event handler updates the circle’s `cx` and `cy` coordinates via React’s `useState` and `useCallback` hooks. The circle starts centered and has a fixed radius of 30 pixels. The example demonstrates interactive SVG rendering with React, using only ReactDOM and no external data or visualization libraries.

Mouse follower

A React application renders a single circle inside an SVG that follows the mouse cursor across the viewport. The component tracks pointer coordinates using a `useState` hook and updates the circle's `cx` and `cy` attributes on every `mousemove` event via a `useCallback` handler. Rendering relies on React 16.9 for state management and SVG creation, with D3 v5 loaded but not actively used for this behavior. The circle starts centered at 480 by 250 pixels and moves smoothly in response to user input.

mouse follower

A circle follows the mouse position inside an SVG canvas, updating its center coordinates in real time as the pointer moves. The React component uses the `useState` hook to track the mouse's `clientX` and `clientY` values, which are set through an `onMouseMove` event handler on the SVG element. The circle's radius is fixed at 30 pixels, and its position is rendered directly as SVG `cx` and `cy` attributes. The example demonstrates state-driven rendering with React 17 and DOM event handling without external data sources.

A program that follows your mouse with a circle.

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The code uses React's `useState` hook to track the cursor's client coordinates and re-renders the circle's `cx` and `cy` attributes accordingly. The example imports `range` from d3.v7 and builds an SVG element with a mouse-move event handler that captures the cursor's position. No data visualization occurs; the interaction is purely a demonstration of event handling and state-driven SVG rendering in a React environment.

A Program that follows your mouse with a circle

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position in real time. The visualization uses React state to track the cursor's clientX and clientY coordinates, triggered by an onMouseMove event handler on the SVG element. Built with React 16.9 and D3 v7, the circle is rendered directly as an SVG `<circle>` element, with its cx and cy attributes bound to the current mouse position. No data source is involved; the interaction is purely event-driven.

follow_circle

A React application renders an SVG circle that follows the mouse cursor across a 960x500 canvas. The circle's position updates dynamically based on the user's pointer movement, using React's `useState` and `useCallback` hooks to manage and handle mouse events. The component tracks the clientX and clientY coordinates from the mouse move event and sets them as the new center of the circle. This example demonstrates state management and event handling in React while rendering a simple interactive SVG visualization.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example shows how React manages interactive state by tracking pointer coordinates. Using React hooks like `useState` and `useCallback`, the component updates the circle's `cx` and `cy` attributes on every `mousemove` event. The code renders a single `<circle>` element with a fixed radius of 30, initializing mouse position at (0,0) and updating it from `clientX` and `clientY` values.

mouse follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, then renders a single circle element with those coordinates as its `cx` and `cy` attributes. The SVG has a fixed width of 960 and height of 500 pixels, with the circle initially centered at the midpoint.
