{"version":"1.0","type":"rich","title":"HDI Scatter Plot With Color","description":"This scatter plot visualizes the relationship between life expectancy at birth and gross national income per capita for countries in 2021, using the United Nations Development Programme (UNDP) HDI dataset. Each circle represents a country, colored by its UNDP developing region, with opacity revealing dense clusters. The visualization uses D3 v7 APIs including `scaleLinear`, `scaleOrdinal`, `schemeCategory10`, and custom `axes` and `colorLegend` functions to render the chart and legend. The plot shows a clear positive trend between the two variables, with regional groupings potentially identifiable through color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/70fa9ffca1314389b759a866e0ed6d31?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
