{"version":"1.0","type":"rich","title":"map","description":"This example displays a choropleth map of Australia, showing state boundaries and labels with hover-based population tooltips. It uses a Mercator projection centered on the country via `d3.geoMercator()` and renders geographic features as SVG paths through `d3.geoPath()`. State polygons are styled with a light fill that darkens on mouseover. The map loads GeoJSON data from a remote gist, and labels are positioned using `path.centroid()`. A custom tooltip div reveals the population property for each state on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/50e967595f57421089c8d71855f8f17d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
