This chart displays the population of the top ten most populous countries in 2018 using a dot plot. Each circle’s horizontal position encodes population size, while the vertical axis lists country names. The visualization uses D3 v5 to scale the data and render SVG circles, with a custom tick formatter converting values to billions. Data is loaded from a local CSV file and multiplied by 1000 to represent actual population counts. Gridlines and axis labels are styled via CSS.
