This bar chart displays the top 10 most populous countries, with each country’s population represented by a horizontal bar. The visualization includes a zoom feature for exploring the data and interactive tooltips that show exact population values on hover. Built with React and D3 v5, it uses `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the SVG chart. The code employs `d3.zoom` for panning and zooming, and `transition.attr` for smooth opacity changes during mouse interactions, with data loaded from a CSV file.
