This bar chart displays the top 10 countries by 2020 population, with horizontal bars ranked vertically. The visualization uses React for component structure and state management, while D3’s `csv` loads and parses the UN population data, and `scaleLinear` and `scaleBand` map values to pixel positions. SVG elements—including `rect` bars and axis ticks—are rendered directly by React, with D3’s `max` and `ticks` methods driving the axis generation. The chart adapts to the browser window size and includes labeled axes.
