{"version":"1.0","type":"rich","title":"United States of Voronoi Tweening","description":"This visualization animates a tween between the geographic outlines of US states and their Voronoi cell boundaries, generated from state capitals via d3.voronoi. The map uses a Mercator projection and toggles between each state's projected border and its Voronoi polygon every two seconds, with a custom shape interpolation function that redistributes points equally along each side of the destination shape to avoid rounded or skipped corners. A clip path confines the animation to the state boundaries, and capital cities are marked with small circles. The transition is built with d3.v4 SVG elements and includes a reusable shapeTween.js module with two tweening approaches, one based on side-length distribution and another on proportional path length.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-50d4ab8dd53d13a00d5d8f1b6393f083?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
