This bar chart displays the populations of the ten most populous countries in 2017, ordered by country name along the y-axis and scaled by population count along the x-axis. Built with React and D3 v5, the visualization uses `scaleLinear` and `scaleBand` to map data, `axisLeft` and `axisBottom` for ticks, and SVG `rect` elements for bars. The data is loaded from a CSV file and multiplied by 1000 to reflect actual population figures.
