{"version":"1.0","type":"rich","title":"United States of Voronoi Tweening w/ borders","description":"This animated visualization transitions U.S. state boundaries between their geographic shapes and Voronoi cells computed from state capitals. Using d3.v4 and SVG, each state polygon tweens between its projected geographic outline and its Voronoi cell, with a second border layer appearing in red during transitions to highlight the differences. Colors, strokes, and capital points shift as the shapes morph, with a custom shape-tweening function that distributes points along each side of the destination shape to avoid rounded or skipped corners. A known rendering-order bug causes some borders, like where \"New Wyoming\" overlaps old Nebraska, to be hidden during the transition.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-3d3567947868d615c418922ad277aeab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
