This bar chart displays the 2018 estimated population of the ten most populous countries, with values in thousands from the UN World Population Prospects. The visualization uses the D3 library (v5) to project data from a local CSV file into an SVG graphic, employing `scaleLinear` for the population axis and `scaleBand` for categorical country labels with a 0.1 padding. Custom tick formatting converts values to billions, and gridlines extend across the chart for readability.
