This example shows a horizontal bar chart ranking the population of the top 10 most populous countries, with a customized axis style. The chart uses d3.csv to load the data, d3.scaleLinear and d3.scaleBand for scaling, and d3.axisLeft and d3.axisBottom to generate the axes. The code removes default axis lines and domain paths, then applies custom styling via CSS for tick labels, grid lines, and a title. The visualization renders to SVG elements.
