{"version":"1.0","type":"rich","title":"7.-Mouse Follower (React)","description":"A bright circle trails the user's pointer as it moves across an SVG canvas, resetting to the canvas center on load. The React app tracks mouse coordinates with `useState` and an `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes. It uses D3 v7 for SVG rendering within a React 17 UMD setup, with the circle’s position bound directly to the pointer’s client coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1dc41b30058240d89a5d7a797219f990?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
