{"version":"1.0","type":"rich","title":"Commutes 2012","description":"Commutes 2012 visualizes commuter flows between Dutch municipalities using a choropleth map. Clicking a municipality recolors all regions by the number of residents working there, with darker shades indicating higher counts. Animated arrows, rotated via `d3.transition` with an elastic ease, point from each municipality toward the selected destination, with arrow lengths scaled proportionally to commuter volume. Built with D3 v3, it uses `d3.geo.path`, `d3.geo.mercator`, and `d3.behavior.zoom`. Data comes from CBS Statline, rendered as SVG with interactive zoom and pan.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-167e0df234eda826cb3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
