{"version":"1.0","type":"rich","title":"Zip Codes","description":"This visualization plots every U.S. ZIP code as a small square on an Albers USA projection, with each point colored by the first digit of its ZIP code. It uses the `vega-lite-api` to construct a layered specification, leveraging `vl.markSquare`, `vl.longitude`, and `vl.latitude` encodings. The data is loaded via `d3.csv` from a GitHub gist, and rendering is handled by Vega-Lite with the `geo-albers-usa-territories` projection. The map fills the browser window and includes a tooltip showing the full ZIP code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3292a8f2de6547d4b1fe16e84b5275c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
