{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map displays countries with a uniform green fill, turning red on hover while the ocean remains light blue. The visualization uses an orthographic projection, rendering country boundaries as SVG paths via the `geoPath` and `geoOrthographic` functions. It loads world map data from the `world-atlas` package (50m JSON and TSV files) and processes TopoJSON features with the `topojson` library. The `zoom` interaction allows panning and scaling the map through SVG transforms, with country names shown in tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9571114002e64b8fb910323a27a1298b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
