{"version":"1.0","type":"rich","title":"Fork of Smiley Face Part III","description":"A mouse-driven smiley face follows the cursor across an SVG canvas. The face is a single orange circle rendered with React state tracking the mouse position. The code uses React hooks `useState` and `useCallback` to update the circle's `cx` and `cy` attributes on every `mousemove`. D3's `arc` function is imported but unused in this implementation. The example demonstrates simple React-D3 integration with direct SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/625a9aedc9824e918a8f18b2e5595b16?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
