{"version":"1.0","type":"rich","title":"practice project","description":"This practice project demonstrates a simple smiley face rendered as an SVG graphic using React and D3. The visualization shows a yellow circle with a black stroke for the face, two black eye circles, and a mouth formed by a D3 arc path. The component uses React’s declarative JSX to define SVG elements, while the `arc()` API from d3-shape computes the mouth’s curved path geometry. Coordinates are calculated relative to the SVG’s center, with fixed offsets for eyes and mouth radius controlling the facial features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2cff0fc65da4f47b3d9610433caacc4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
