{"version":"1.0","type":"rich","title":"Project Momentum","description":"This visualization presents LEGO set data grouped by theme as a multi-layered pie chart, where each wedge shows the total count of sets, with semi-transparent inner arcs indicating the proportion of sets priced under $100 and under $50. The chart uses D3.js APIs including `pie`, `arc`, `scaleOrdinal`, and `schemeCategory10` to generate and color the arcs, while `Object.groupBy` and custom reduction logic aggregate the imported `@Landaman/lego-csv` data. The top eight themes are labeled, with remaining sets consolidated into a \"Miscellaneous\" category, and SVG path elements are styled with stroke and opacity to create depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f4b26c106a4455d819c2e1986cd8796?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
