{"version":"1.0","type":"rich","title":"OpenLayers Dark Basemap","description":"This example combines OpenLayers and React to create an explorable dark-themed map. It uses a Stamen toner-lite basemap layered with D3.js cartographic elements, including a Natural Earth projection, geographic graticules, and circles sized to represent data points from a CSV dataset of city deaths. The map’s muted background is achieved through CSS filters that invert and reduce opacity, while OpenLayers manages panning and zooming.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dce125714434e458fd8a9f71fee9bf4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
