Ordinal Scatter Plot
This ordinal scatter plot displays the population of the top 10 most populous countries, with each circle positioned along a categorical y-axis and a linear x-axis scaled in billions. The visualization uses d3.csv to load the data, d3.scalePoint for the ordinal y-axis, and d3.scaleLinear for the population values. Axes are generated with d3.axisLeft and d3.axisBottom, while the x-axis tick labels format numbers using d3.format with a custom 'B' suffix for billions. Data originates from the 2017 United Nations World Population Prospects report.
