This example visualizes the population of the top 10 most populous countries in 2018, sourced from the World Population Prospects 2017. The bar chart encodes country on the y-axis using a band scale and population on the x-axis using a linear scale. Built with D3 v5, the visualization renders as an SVG, using `scaleLinear` and `scaleBand` for axes, and `axisLeft` and `axisBottom` for tick labels. Population values are read from a CSV file and multiplied by 1000 to reflect actual figures. Steelblue rectangles represent the data.
