{"version":"1.0","type":"rich","title":"Kids Shape and Color App","description":"This interactive app lets children explore color, size, and shape by clicking through three control panels. The selected attributes combine into a single large symbol rendered in the center. Built with D3 v5, the code uses SVG `symbol()` generators for circles, squares, and triangles, with click handlers updating state via `onCircleClick` and `onClick` callbacks that re-render the mark.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40dd647950ab4a63b825ee005a82e6b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
