{"version":"1.0","type":"rich","title":"sernec project data","description":"This visualization maps the SERNEC herbarium collection, showing the geographic distribution of plant specimens across the southeastern United States from 1800 to the present. It uses D3’s `d3.forceSimulation` to position and cluster data points by location and taxonomy, while `d3.geoPath` renders the regional map backdrop. Specimen density and temporal range are encoded through point size and opacity, with the underlying dataset sourced from the SERNEC project’s public gist. The rendering approach emphasizes spatial patterns of biodiversity without interactive filtering or animation.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-3777706?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
