This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5 with an SVG rendering, employing `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis, along with `d3.axisLeft` and `d3.axisBottom` for tick marks. Data is loaded from a CSV file and processed by multiplying population values by 1000. The chart includes an accompanying video tutorial linked in the README.
