This bubble chart shows the correlation between GDP per capita, life expectancy, and population for ten countries. Each circle’s x-position represents GDP, y-position represents life expectancy, and its radius encodes population size. The visualization uses D3 v7 with SVG rendering and animation, reading data from a CSV file. It includes axis labels, tooltips on mouseover, and legends for both bubble size and country color, which uses the `d3.schemeTableau10` scale.
