This example visualizes the 2018 population estimates of the ten most populous countries as horizontal bars. The chart uses D3 version 5.6, with an SVG canvas. The code employs D3's `scaleBand` and `scaleLinear` to map country names and population counts to y- and x-coordinates, respectively, while `axisLeft` renders the y-axis labels. Data is loaded asynchronously from a CSV file via `csv()` and parsed into numbers, with each bar’s length encoding the population value.
