{"version":"1.0","type":"rich","title":"Untitled","description":"This example visualizes a dataset of location-based check-ins as a dynamic particle system, where each point represents a recorded visit and its position is derived from aggregated geographic coordinates. The visualization uses a custom WebGL rendering loop via Three.js to draw and animate thousands of glowing, color-coded particles that cluster around urban hotspots, with brightness indicating density. The underlying data is processed using a force-directed simulation (d3.forceSimulation) to spread overlapping points, while the geographic layout is projected using d3.geoMercator and d3.geoPath for reference boundaries. A slider lets users scrub through time, revealing how check-in patterns shift across hours of the day.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
