This map displays California’s zip code boundaries as green polygons with thin black outlines on a gray background. It loads GeoJSON data from the OpenDataDE GitHub repository and renders the state using a projected `geoMercator` centered at coordinates [-120, 37], with `d3.geoPath` generating the SVG path strings. The visualization sets the map scale to 3.3 times the width and translates it to the center of the SVG canvas, delivering a static, full-state view without interactivity.
