{"version":"1.0","type":"rich","title":"Untitled","description":"This example presents a world map with red circles marking a curated list of cities, including Tokyo, London, and Easter Island. The map is built using D3.js version 3 with a Mercator projection and TopoJSON data for country boundaries. Users can pan and zoom the map via the d3.behavior.zoom API, while a tooltip-like styled div is defined but not activated. City coordinates are projected onto the SVG canvas using d3.geo.path.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b2504527a7d44d449d07dd8b8b9e78b5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
