This visualization displays a horizontal bar chart ranking the populations of ten countries using data from a CSV file. The chart encodes population values on the x-axis and country names on the y-axis, with bars rendered as SVG rectangles. The code uses d3.csv for data loading, d3.scaleLinear for the population scale, and d3.scaleBand for the categorical country scale. The example demonstrates a step-by-step bar chart creation process, with margins and an SVG container sized at 960 by 500 pixels.
