{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example visualizes the world’s countries as filled polygons on a natural Earth projection, with oceans rendered in blue and landmasses in light green. It uses D3.js v5’s `geoNaturalEarth1` projection and `geoPath` to generate SVG paths, while TopoJSON’s `feature` function extracts country boundaries from a 110m world-atlas GeoJSON dataset. The code draws a sphere background and then overlays each country’s path, applying thin black strokes for borders.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f80b810d61c74df08405e8532c50a04b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
