{"version":"1.0","type":"rich","title":"Assignment8_sowjanya_countryMap","description":"A choropleth of the United States displays median age by state, using a pastel threshold color scale with seven bins ranging from under 32 to over 46 years. The visualization loads US Census-derived CSV data and TopoJSON state boundaries via `Promise.all`, then renders each state as an SVG `path` using `d3.geoPath` with the `geoAlbersUsa` projection. Hovering reveals a tooltip with the state name and median age, while a horizontal legend beneath the map shows the color breaks. The code relies on D3 v7 and the topojson-client library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9a8b055d5fd44e8b25f91a887aea980?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
