{"version":"1.0","type":"rich","title":"Butter Macronutrients","description":"A pie chart visualizes butter's macronutrient composition per 100 grams, showing fat as the dominant slice at 81.11g alongside smaller protein and carbohydrate segments. Clicking any slice highlights it with a darker stroke and full opacity while dimming others. Built with D3 v7, the chart uses pie and arc generators with a custom start angle for rotation, and labels position via arc centroid calculations. A unidirectional data flow pattern manages selection state, with the SVG rendered through d3.select and join operations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f78a3c7627b04f1dae721ba3c0af0b01?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
