This visualization displays the top 20 countries ranked by GDP, using horizontal bars to show population values. The chart is rendered as an SVG using React and d3.v5. D3’s scaleBand and scaleLinear map country names and population data from a CSV file, while the x-axis tick marks are drawn with line and text elements. The data source is a GitHub gist, and the bars are colored green with a blue gridline for scale reference.
