{"version":"1.0","type":"rich","title":"pie chart for percentage with transition, gradient color and mouse over *changed*","description":"A donut chart displays a single percentage value with a smooth animated transition, using a gradient fill that shifts from red to green as the percentage increases. The chart includes a mouseover effect that highlights the arc and bolds the percentage text. Built with React and D3 v5, the visualization uses SVG paths, `d3.arc` for the donut shape, `transition.attrTween` for the animation, and a linear gradient defined in the SVG `defs` section. The percentage updates are driven by `d3.interval`, with the input data hardcoded as zero.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/636eb623dc1d4051bd582b6abdb4d578?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
