This bar chart displays the population of the top 30 countries in 2020, with a vertical layout where each country is listed along the y-axis and population counts extend horizontally. The data originates from the Kaggle World Population Prospects 2020 dataset, loaded as a CSV. The visualization uses D3 v5 with scaleLinear, scaleBand, axisLeft, and axisBottom to position bars and axes, while customizing tick formatting to abbreviate numbers with suffixes like “B” for billions. The SVG rendering includes styled rectangles and a custom font from Google Fonts.
