{"version":"1.0","type":"rich","title":"Map of top-rated restaurants in Greater Boston","description":"This choropleth map visualizes the distribution of top-rated restaurants (4 stars or higher) across Greater Boston municipalities, using a red color scale where darker shades indicate higher restaurant counts and grey represents areas without data. The map is interactive, supporting zooming via d3.zoom and hover tooltips that display each town's name and restaurant count. Built with D3 v5, it uses d3.geoPath with a geoIdentity projection and topojson to render Massachusetts town boundaries. The data comes from the public Yelp dataset, filtered and aggregated by city.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b85e5f4e65d40f6883447cfc8fedea7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
