This horizontal bar chart displays the populations of the top 30 countries in 2020, sorted by country name. The visualization uses D3.js v7 with an SVG rendering approach, employing `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis to position the light green bars. The data is loaded from a CSV file hosted on GitHub, with the population values formatted as billions (e.g., "1.2B") on the x-axis. Both axes include custom labels, with the x-axis labeled "POPULATION-2020" and the y-axis labeled "Countries".
