This bar chart visualizes population data for ten countries, sourced from a CSV file that pairs country names with their population figures. The code uses the d3.csv function to load the data and then prepares to render it with D3 v5. The visualization is built within an SVG container, with the chart’s dimensions read directly from the SVG attributes. While the current code logs the parsed data to the console, the bar chart rendering itself depends on the bundled JavaScript referenced in the HTML.
