{"version":"1.0","type":"rich","title":"test world map block","description":"This example renders a static world map onto a canvas element using D3 v4 and TopoJSON. It uses a `d3.geoEquirectangular` projection and `d3.geoPath` to draw country boundaries from the world-atlas 110m dataset. The map is displayed in muted earth tones with a red stroke only on the `.names` class, though no name labels are actually generated. The code appends an SVG layer to the canvas, but final output relies on SVG paths for the geographic features.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f42062258d309e5a24583f080a5460d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
