This example shows a horizontal bar chart of the ten most populous countries, using population values from a CSV file. The chart customizes its axes by removing the default domain lines and tick lines from the categorical y-axis, and by applying a custom tick formatter to the linear x-axis that abbreviates large numbers (e.g., converting "G" to "B"). The visualization is built with D3 v7, using `scaleLinear` and `scaleBand` for scales, `axisBottom` and `axisLeft` for axes, and SVG rendering.
