{"version":"1.0","type":"rich","title":"Untitled","description":"An interactive scatterplot maps World Health Organization data, plotting urban population growth against the percentage of the population living in urban areas. Each circle represents a country, with its fill color encoding the total fertility rate using a threshold scale and a blue color scheme; missing values appear pink. The visualization uses D3.js 5.15.0, including `d3.scaleThreshold`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, to render axes, legends, and circles as SVG with mouseover events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/822fd371e2584b67acc6cd50e9bc8bb0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
