{"version":"1.0","type":"rich","title":"Fork of Project Momentum v3","description":"This visualization displays the distribution of LEGO sets by theme, using a nested donut chart where three concentric arcs per slice show the total count, the number of sets priced under $100, and those under $50. Hovering dims non-selected arcs via opacity adjustments. The chart is built with D3’s `pie` and `arc` generators, with data imported from the `@Landaman/lego-csv` package and grouped by theme. Color mapping uses `scaleOrdinal` with `schemeCategory10`, while labels and leader lines are positioned using `arc().centroid`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d18052ce5524fccafa11b8f6e68b67f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
