This horizontal bar chart shows the populations of 20 countries in 2010, ordered from largest to smallest. The visualization uses D3 v7 with an SVG rendering approach, fetching data from a GitHub-hosted CSV file. It employs `scaleLinear` for the population axis, `scaleBand` for country categories, and custom styled grid lines drawn with SVG elements. The chart displays blue bars with formatted tick labels using `d3.format` and includes axis labels for both country names and population values.
