{"version":"1.0","type":"rich","title":"GDP Choropleth Viz","description":"A world map colored by GDP per capita displays each country’s economic standing for a selected year, controlled by a slider. Hovering over a country updates a line plot showing that nation’s GDP trend over time, with red and green reference lines marking the current year’s value. The visualization combines a `d3.geoEqualEarth` projection rendered as SVG with `d3.scaleLinear` color encoding, alongside a linked line chart built using `d3.line` and axis components. GDP data originates from a CSV file, while country boundaries use a GeoJSON source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72eea4d8833b4d7ba7c1df606c012291?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
