{"version":"1.0","type":"rich","title":"Fork of Label Filtering Algorithm Prototype","description":"This visualization demonstrates a label placement algorithm for maps and scatter plots, showing city names positioned without overlapping. It projects world cities using a Natural Earth projection and renders population density as colored contours. The code uses D3 methods like `geoNaturalEarth1`, `contourDensity`, and `scaleSequential` for the map, while collision detection relies on the RBush spatial index. Labels are filtered by population threshold and hidden when their bounding boxes intersect, with data from the visionscarto-world-atlas and worldcitiesReduced datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa2ee175a15e4c6ea21b7e81cc752cd7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
