{"version":"1.0","type":"rich","title":"Fork of Zip Code Trails","description":"This example renders 960 by 500 pixel U.S. zip code trails as thin colored lines. It uses the `albersUsa` projection to display the geographic data derived from the `zipcodes.csv` dataset. The code employs the `vega-lite-api` to construct a line mark, with `d3` providing a hue-based color scale for the first three digits of each zip code, and a filter removes non-continental states. A fixed color mapping with nine hues visualizes regional groupings across the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab0f68c6672a43ac90bebd5fafd370aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
