{"version":"1.0","type":"rich","title":"D3 Spin Art","description":"This interactive visualization lets users draw freehand lines or dots on a rotating canvas, producing spiral-like patterns whose appearance changes with speed. A vertical slider controls revolutions per minute, a color palette selects stroke colors, and radio buttons toggle between line and circle draw styles. The code uses D3 v4 transitions with a linear easing function to animate the SVG group’s rotation, while drag events append polyline or circle elements to the rotating group.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-055217b55a7e152790895c006f6693d1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
