This bar chart displays the populations of the ten most populous countries, based on 2018 estimates from the World Population Prospects 2017. The visualization uses d3.csv to load the data, d3.scaleLinear and d3.scaleBand to map population values and country names to the chart’s SVG coordinates, and d3.axisLeft and d3.axisBottom to render the axes. Rectangles are appended to represent each country’s population, with the x-axis scaled in increments of one million.
