This example presents a vertical bar chart that compares the 2023 population of various countries, with values scaled in millions on the y-axis and country names on the rotated x-axis. The visualization is rendered as SVG, using D3 v5’s `scaleBand`, `scaleLinear`, and `axisBottom`/`axisLeft` to position and label the bars. Data is loaded asynchronously via `d3.csv` from a remote raw GitHub dataset, and bars are drawn with `rect` elements filled in skyblue. The chart includes custom tick formatting and axis titles for clarity.
