This animated bar chart displays the populations of the ten most populous countries, using horizontal bars colored on a linear scale from orange to brown. The visualization loads data from a CSV file and multiplies each population value by 1,000 for display. Built with D3 v5, it uses `scaleLinear` for the x-axis and population-based coloring, `scaleBand` for the y-axis categories, and `axisBottom` with tick formatting that abbreviates large numbers. Bars animate in over one second using `transition` with `easeLinear`, while SVG renders all elements.
