{"version":"1.0","type":"rich","title":"D3 Marker Clustering w/Unified Mercator & Tile","description":"This example demonstrates a D3 marker clustering visualization that combines a Mercator projection with slippy-map-style tile loading. The map uses OSM tiles rendered from a unified Mercator projection, while markers are drawn on an SVG canvas. A custom force simulation, based on D3's force module, handles clustering by applying a collision force with an absorption rule: when two markers overlap, the larger one absorbs the smaller, growing in radius and count. The underlying tiles and markers stay synchronized through a unified projection and zoom transform, providing a smooth pan-and-zoom experience with dynamic marker merging.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-3b8c856445b1f297dadff7f86d380095?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
