This example displays a land use statistics map of Switzerland, rendering municipal boundaries as black vector paths on a light background. It loads GeoJSON data from `ch_municipalities.geojson` and projects them using `d3.geo.mercator()` with a fixed scale and center point, then translates the projection to fit a 900 by 600 pixel SVG container. The code uses `d3.geo.path()` to generate the path data for each feature, appending `path` elements to the SVG via a data join. The map is static, with no interaction or additional styling beyond the basic class assignment.
