{"version":"1.0","type":"rich","title":"Pie charts labels","description":"This donut chart displays categorical data with labels connected to each slice by thin polyline leaders. A \"randomize\" button triggers smooth transitions between datasets. The visualization uses D3 v3's `d3.layout.pie` and `d3.svg.arc` to compute slice geometry, while `transition.attrTween` animates changes in slice paths, label positions, and connector endpoints. Labels alternate between left and right alignment depending on their angle, and the SVG rendering includes distinct groups for slices, labels, and lines.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-5adf28e7b13447b8a1e309ed98fcb07a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
