A bar chart displays the population of ten countries, using a vertical bar for each nation with its value labeled above. The visualization is rendered as an SVG using D3 v5, with `d3.scaleBand` for the x-axis positions and `d3.scaleLinear` for the y-axis scale. The data is loaded from a CSV file via `d3.csv` and formatted with tick labels, while bars are styled in steelblue and positioned through transform translations. The code removes gridlines and axis domains for a cleaner presentation.
