Making a Bar Chart
This bar chart displays the populations of the ten most populous countries, based on 2018 estimates from the United Nations' World Population Prospects. It uses D3 v5 APIs including `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data, map values to positions, and render axes as SVG. Population values are multiplied by 1000 and represented as horizontal bars, with country names on the y-axis and population on the x-axis. The chart is styled with steelblue rectangles and larger text for readability.
