This bar chart displays the population of the top 10 most populous countries, using a horizontal layout where each bar’s length corresponds to population size. The visualization is built with D3 v5 within a React framework, rendering to an SVG canvas. The code loads data from a CSV file, applies a linear scale for population and a band scale for country names, and adds axis labels and a title. Styling is handled through a separate CSS file, with steelblue bars and custom fonts for readability.
