This interactive bar chart displays the population of the top ten countries in the year 2000, using horizontal bars to compare values. The visualization is built with React and renders to an SVG canvas. It uses D3 version 5's `scaleBand` and `scaleLinear` to map data from a CSV file loaded via `d3.csv`, with axes and marks created by custom components. A tooltip shows the formatted population value when hovering over a bar.
