Built with React 16.9, the app tracks mouse movement via an `onMouseMove` handler on the `<svg>` element, updating the circle's `cx` and `cy` coordinates through React state. The initial circle position is centered at 480, 250, with a fixed radius of 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34a10a1072184beb81597a96469df284?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
