{"version":"1.0","type":"rich","title":"Flight Animation","description":"This animated visualization plots historic sailing routes from OpenFlights data as glowing yellow arcs on a dark Stamen toner map. Using OpenLayers and D3, each route is drawn progressively as a great-circle arc between its source and destination ports, with the line growing over time at a constant rate. Flights are added sequentially with a delay, creating a staggered animation as the arcs trace their paths across the globe. The map uses the EPSG:3857 projection and the animation runs continuously via OpenLayers' postcompose event, rendering each flight's partial trajectory frame by frame until complete.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-14dabd536a6d433ff867659797602f4e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
