Making a Bar Chart
This example presents a horizontal bar chart of the top 10 most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization customizes D3 axes by removing domain lines and tick lines, formatting population values with `format('.3s')` to abbreviate billions, and adding a title and axis label. Data is loaded from a CSV file, scaled with `scaleLinear` and `scaleBand`, and rendered as SVG rectangles. The code imports specific D3 v5 modules including `csv`, `scaleBand`, `scaleLinear`, `axisLeft`, and `axisBottom`.
