{"version":"1.0","type":"rich","title":"Iceland TopoJSON -pan/zoom","description":"This example displays a topographic map of Iceland using the TopoJSON format, with individual polygons colored on a green-to-white scale based on elevation data. The map supports interactive pan and zoom through the D3.js `d3.behavior.zoom` API, which applies translation and scaling transforms to the SVG group containing the projected paths. The visualization renders geographic features via `d3.geo.path` with a Mercator projection, and data is sourced from the National Land Survey of Iceland.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4686541?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
