This bubble chart visualizes the correlation between birthrate, life expectancy, and GDP across fourteen countries, using a D3.js SVG rendering with animated transitions. GDP scales bubble radius, while life expectancy and birthrate map to the x- and y-axes, with colors assigned via a turbo color scale. A tooltip displays each country’s name on hover, and a legend shows GDP values and country color keys. The chart uses D3’s CSV loader and linear scales, with data from the included CSV file.
