{"version":"1.0","type":"rich","title":"Mouse mover","description":"A React component tracks the mouse position over an SVG canvas and renders a black circle that follows the cursor. The circle’s center coordinates are updated through React’s `useState` hook and a `handleMouseMove` callback triggered by the SVG’s `onMouseMove` event. The code uses D3 v7 for SVG rendering within a React 17 application, with the circle’s radius fixed at 30 pixels and the initial position set to the center of a 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
