{"version":"1.0","type":"rich","title":"arc tween example","description":"A single SVG arc animates from zero to a full circle over one second, visually representing progress toward a goal. The code first draws a complete gray background ring, then overlays a black arc whose end angle transitions from 0 to 2π using `d3.svg.arc` and `transition.attrTween` with `d3.interpolate`. When the arc reaches full completion, a CSS transition changes its fill to orange via the `complete` class. The example uses D3 v3 and relies on SVG path rendering.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-64c72b2c4a41aafe651d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
