This bubble chart shows the five most populous countries in 2020, comparing their populations in 2016 against 2020 on the x- and y-axes. Bubble size encodes population growth between those years, with color distinguishing each country and labels identifying them. The visualization uses d3.csv parsing with delimiter detection, d3.scaleLinear for both axes, d3.scaleSqrt for bubble radius, and d3.scaleOrdinal with Tableau10 colors. Hovering reveals a tooltip with exact values, rendered via SVG and D3 v7.
