This stylized bar chart displays the top 10 most populous countries, using horizontal bars that extend from the left axis to represent population sizes. The visualization employs React with D3 v5 functions like `scaleBand` and `scaleLinear` for positioning, while rendering as an SVG. The chart includes customized Poppins typography, styled axes with muted tick colors, and a teal fill for the bars. Data comes from the United Nations World Population Prospects 2019, loaded via D3's `csv` function, with tooltips formatting values using D3's `format` to display billions.
