{"version":"1.0","type":"rich","title":"Fork of OpenLayers Dark Basemap","description":"This example combines OpenLayers and D3 to create an interactive map with city data. The React component overlays D3-rendered circles, sized by death counts from a CSV dataset, onto an OpenLayers basemap using the Stamen toner-lite tiles. The map uses `ol.View` for panning and zooming, while `d3.geoNaturalEarth1` and `d3.geoPath` draw geographic features like land, graticules, and city points. The basemap is filtered with CSS to invert its colors and reduce opacity, producing a muted dark background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1664efe73f8c46e78cf34f7a1f0cd35f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
