This scatter plot displays the population of each continent in 2018, with circles plotted along a linear population scale and a point-based categorical axis for continents. The visualization uses D3 v5 APIs including `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` to render SVG circles and axes. Population values from the CSV are formatted with abbreviations (e.g., “B” for billions), and grid lines extend across the plot. The chart also includes axis labels and a title, styled with custom CSS for fonts and circle transparency.
