{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part II","description":"A single circle tracks the mouse cursor inside an SVG canvas, moving in real time to mirror the pointer’s position on screen. Built with React, the app uses the `useState` hook to store the current mouse coordinates and `useCallback` to handle the `mousemove` event, updating the circle’s `cx` and `cy` attributes. The rendering relies on React DOM to manage the SVG elements, with the circle’s radius fixed at 30 pixels within a 960-by-500 viewport. No external data source is used; the interaction is purely event-driven.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/210f1fd7b25f4a84b5c337565dcdf9e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
