Fork of Mouse Follower
A circular SVG element tracks the mouse cursor's movement across the screen, updating its position in real time. The React application uses a `useState` hook to store the current mouse coordinates, which are updated via an `onMouseMove` event handler on the SVG canvas. The visualization is rendered using React's declarative SVG markup, with the circle's `cx` and `cy` attributes bound directly to the state values, producing a smooth following effect as the cursor moves.
