This bar chart visualizes population data for six countries using D3.js v5, with orange bars drawn in SVG. The code loads data from a CSV file, maps country names to the x-axis using `scaleBand`, and population values to the y-axis with `scaleLinear`. Axes are added via `axisBottom` and `axisLeft`, while the chart is rendered by appending rectangles to an SVG group, with margins and dimensions derived from the SVG element’s attributes.
