{"version":"1.0","type":"rich","title":"Fork of Grid Sampling on Census Tracts - Optimized","description":"This example visualizes New York City census tracts on an orthographic globe projection, styled as a choropleth-like grid of points sampling each tract’s interior. The visualization shows demographic data from the U.S. Census Bureau’s 2023 ACS estimates. It uses `geoOrthographic`, `geoPath`, and a custom `map` module to render tract boundaries and a uniform grid of points, with an RBush spatial index and turf’s `booleanPointInPolygon` to test which grid points fall inside tracts. Drag and zoom interactions adjust the globe’s rotation and scale via `d3.drag` and `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4e4e39d877c496eb97e08091fad7ef0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
