{"version":"1.0","type":"rich","title":"d3Edge_V5-drawRoutes-v0.1","description":"This example builds an interactive map of Zurich and draws transit routes from a GeoJSON file using D3 v5. It demonstrates a modular map component that initializes a Mercator projection and sets up SVG rendering for geographic paths. The code explores loading GeoJSON data asynchronously via `d3.json` and a promise-based `.then()` callback, while a commented data manager module shows an alternative approach using `d3.dispatch` for custom events. Route data comes from the D3Edge GitHub repository, and the visualization uses `d3.geo.mercator` and `d3.geo.path` for projection and path generation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e61a29949f784ecd973317857a7c1561?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
