This bar chart shows the population of the ten most populous countries, with vertical bars extending from a truncated y-axis. It customizes axes by removing domain lines and tick lines on the left, and uses a tick formatter with d3.format to convert values from billions to a readable scale with ‘B’ suffix. The chart labels the x-axis ‘Population’ and applies a title. The visualization is built with d3.v7, using scaleLinear, scaleBand, axisLeft, and axisBottom, rendering as SVG.
