{"version":"1.0","type":"rich","title":"Assignment 2 World map","description":"This example displays a world map using a Mercator projection, with each country as a gray polygon outlined in red. The visualization loads GeoJSON country boundaries from a remote GitHub repository and renders them as SVG paths. It uses D3.js v6 APIs, including `d3.json` to fetch the data, `d3.geoMercator` for the projection, and `d3.geoPath` to generate the path data for each feature. The map is fitted to an 800×600 viewport using the projection’s `fitSize` method, with a light gray background applied via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8408f7787622422b82aa443c8c6471b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
