{"version":"1.0","type":"rich","title":"Pulsing markers in Mapbox GL JS","description":"Pulsing markers in Mapbox GL JS animate mountain peak labels from the Natural Earth elevation points dataset, with a yellow ring effect that expands and fades around each numbered marker. The map uses Mapbox GL JS v0.12.2 with a streets style, adding two symbol layers from the same GeoJSON source. A `requestAnimationFrame` loop running at 30 frames per second adjusts text opacity and size properties on one layer, creating the pulsing effect while the base layer remains static.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-6d979af7beb969cd933d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
