This scatter plot displays population figures for ten countries using a bar-like layout with circular markers. The visualization includes interactive dropdown menus (labeled A, B, C) and employs D3 v6 APIs such as `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` to render the SVG chart. Data is loaded from a CSV file via `d3.csv`, with population values scaled by 1000. Custom gradient fills are applied to circles and text via SVG `linearGradient` definitions.
