{"version":"1.0","type":"rich","title":"MI ZIP Code Pop.","description":"This visualization shows the population distribution across Michigan ZIP codes, with each ZIP code region colored and opacified based on its population density. The map uses an azimuthal equal-area projection, rendering ZIP code boundaries and administrative land features as SVG paths via `d3.geoPath`. Population data from michigan-demographics.com drives a linear opacity scale (`d3.scaleLinear`), mapping lower populations to more transparent regions and higher populations to more opaque ones. Hovering over a region reveals the ZIP code and its population in a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/160caf7ee4c64e26a5ab4465165c3210?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
