{"version":"1.0","type":"rich","title":"Mapbox Storytelling","description":"This interactive map tells a scrollytelling story about Philadelphia’s bicycle infrastructure. Using the Mapbox GL JS API, a fixed map is paired with scroll-driven chapters that reveal and hide separate layers—such as bike lanes, Indego bike-share stations, and trail networks—by adjusting their paint property opacities. The Scrollama library and Intersection Observer handle the chapter activation, while a JavaScript config file defines the narrative content and camera positions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b7ce02e37ee41cfa9370d1e7b6b007e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
