This stylized bar chart displays the top 10 countries by projected 2020 population, using horizontal bars whose lengths encode the population values. The visualization pairs a D3.js v5 linear scale for the x-axis with a band scale for categorical country labels, while React renders each bar as an SVG rectangle. The design features custom fonts (Pacifico and Open Sans Condensed) and a distinct color palette for axis ticks and marks. Data originates from a CSV file of UN Population 2019 estimates, loaded via D3's `csv` function, and includes tooltips formatted in billions using `d3.format`.
