{"version":"1.0","type":"rich","title":"three.js - Jotunheimen","description":"A GPS track of a run in Jotunheimen, Norway, is rendered as a single continuous line floating in 3D space using Three.js. The code loads an XML activity file and extracts trackpoints, mapping latitude and longitude coordinates through a D3 transverse Mercator projection into Three.js vector positions, while altitude values are ignored in favor of a fixed z-coordinate. The line is drawn with `THREE.Line` and `LineBasicMaterial`, and the scene uses an ambient light and a perspective camera for a static WebGL view.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8778421?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
