Stylized Bar Chart
This stylized bar chart displays the top 10 most populous countries in 2020, using horizontal bars sorted by population size. The visualization is built with React and D3 v5, employing `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. Data comes from the United Nations World Population Prospects 2019 dataset, loaded via D3’s `csv` method. SVG rendering includes styled axes with tick lines, a population axis label, and tooltips using the native `<title>` element.
