{"version":"1.0","type":"rich","title":"RGB color theory","description":"Five overlapping semi-transparent squares demonstrate RGB color theory by mixing red, green, and blue primaries in various pairings to produce yellow, cyan, and a central white region. The React components `MyRect` and `MyCircle` render SVG rectangles with fixed opacity, positioned via translation transforms. Built with React 16.12 and D3 v5, the example uses static JSX coordinates rather than data-driven layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/267ebd46e8b946319b63c2f1490b73eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
