{"version":"1.0","type":"rich","title":"Arc Chart","description":"This visualization displays a single numeric value as a semicircular arc chart, with the value shown as a large centered label and a colored arc representing its proportion relative to a 0–100 scale. The background arc is gray and semi-transparent, while the foreground arc and text use a color scale that transitions from red through yellow to green. Built with D3 v4, it uses `d3.arc` for the path geometry, `d3.scaleLinear` for both the angle mapping and color interpolation, and SVG rendering. The chart adapts to the window size and rotates the arcs by -90 degrees to start at the top.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7b7bb57156e00d9d6b1fb425251883d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
