Mouse Follower

Mouse Follower

A yellow circle follows the mouse cursor within an SVG canvas as the pointer moves. The visualization uses React hooks and event handling, specifically the `useState` and `useCallback` functions, to track the cursor's `clientX` and `clientY` coordinates and update the circle's `cx` and `cy` attributes. The circle is drawn using React's SVG support, with the D3.js `arc` function imported but not used in the visible code. The canvas size is fixed at 960 by 500 pixels with a circle radius of 30.

A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates, which are then passed to the SVG circle's `cx` and `cy` attributes. The D3 library is imported but only for its `arc` function, which is unused; the rendering relies entirely on React and SVG properties.

A yellow circle follows the mouse cursor across a blank SVG canvas, tracking every movement in real time. The visualization demonstrates React state management, where mouse coordinates update the circle's position via the `useState` and `useCallback` hooks. Rendered as an SVG element, the circle's `cx` and `cy` attributes are bound to the current cursor position. The example uses React 16.9 and D3 v5, with the D3 `arc` function imported but unused, relying instead on React's event handling for interactivity.

A yellow circle follows the mouse cursor as it moves across an SVG canvas. The circle updates its position in real time through React’s `useState` and `useCallback` hooks, which handle mouse-move events. The example uses React and D3 v7, rendering the circle as an SVG element with coordinates derived from the `clientX` and `clientY` properties of the mouse event.

A yellow circle follows the mouse cursor's movement within an interactive SVG canvas. The visualization uses React's `useState` and `useCallback` hooks to track the mouse position, updating the circle's `cx` and `cy` attributes on every movement event. The code integrates React and D3.js version 5, rendering the circle as an SVG element within a React component. The coordinate system is initialized to the center of a 960 by 500 pixel canvas, and the circle is drawn with a fixed radius of 30 pixels.

Mouse Follower

A yellow circle tracks the mouse's position across an SVG canvas. The visualization uses React's useState hook to store and update mouse coordinates, which are captured through the SVG's onMouseMove event handler. D3's arc function is imported but the circle is drawn using standard SVG elements, with React rendering the scene at a fixed 960 by 500 pixel resolution.

Mouse Follower

A yellow circle follows the mouse cursor within an SVG canvas. The circle's position updates in real-time, moving to match the pointer's coordinates on every mouse movement. The visualization is built with React and D3.js, using a stateful component to track cursor position and render the circle. The `useState` hook maintains the current coordinates, while the `onMouseMove` event handler updates them, and ReactDOM renders the SVG element to the page.

Mouse Follower

A yellow circle follows the mouse cursor across a blank, full-window SVG canvas. The example demonstrates a simple interactive mouse-follower pattern where the circle’s center position is updated in real-time based on pointer movement. Built with React and D3 v5, it uses React’s `useState` hook to track mouse coordinates from an `onMouseMove` event, then renders the circle via SVG. D3 is imported solely for its `arc` function, though it is not used for the visualization’s core behavior.
