This bar chart displays the populations of the ten most populous countries, using data from the United Nations World Population Prospects 2017. The chart renders as SVG, with horizontal bars ordered by country name along the y-axis and population counts on the x-axis. The visualization is built with D3 v5, utilizing `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to position the bars and axes. Population values are read from a local CSV file and scaled by a thousand before being mapped to bar widths.
