{"version":"1.0","type":"rich","title":"Gist 8393672","description":"This example visualizes a grid of geospatial tiles covering a region in Romania, with each tile representing a downloadable SRTM elevation data file. The map uses a GeoJSON FeatureCollection and renders polygon boundaries via D3's `d3.geoPath` projection. Each cell is labeled with its tile number, and a hover interaction likely reveals the associated download URL. The visualization relies on D3 for geographic path generation and the underlying data comes from a geomorphology website’s SRTM dataset, making the tile structure and coverage area immediately clear.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8393672?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
