{"version":"1.0","type":"rich","title":"activity 7.1","description":"This interactive visualization shows the movement of flight paths across a global map using a three-dimensional globe. It displays animated arcs that connect various geographic locations, with each path represented by a flowing line that moves from its origin to its destination. The visualization uses Three.js, specifically `THREE.SphereGeometry` and `THREE.Points` to construct the globe and stars, while flight arcs are drawn with `THREE.Line` and animated using `requestAnimationFrame`. The data for flight routes is loaded from a CSV file, and geographic coordinates are projected onto the globe using a custom equirectangular projection function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
