{"version":"1.0","type":"rich","title":"pie chart for percentage with transition, gradient color and mouse over","description":"This example shows a donut chart displaying a percentage value, where the foreground arc animates to its final angle using a repeating transition. The arc’s color shifts through a gradient that changes based on the input percentage, with hover effects highlighting the path by increasing its stroke width and color. Built with D3 v5 in a React framework, the visualization uses `d3.arc`, `transition.attrTween` for smooth angle interpolation, and `linearGradient` definitions for the dynamic color stops.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f89df3a09194b6abccd65351e44a002?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
