{"version":"1.0","type":"rich","title":"Project Momentum v4","description":"This donut chart visualizes the distribution of LEGO sets by theme and price, showing the proportion of sets in eight top themes plus a \"Miscellaneous\" category. It uses D3 pie arcs and labels for each theme, with each arc segment’s color representing its theme and opacity indicating price range (under $50, $50–100, over $100, or unknown). A legend allows interactive highlighting: hovering a price category dims other segments. The visualization is built using D3's `pie` for arc generation, `arc` for path geometry, `scaleOrdinal` with `schemeCategory10` for colors, and a `ResizeObserver` for responsive sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9be4b317a4cc4d21acb1752befb317a3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
