This example shows a horizontal bar chart of population by country, with customized axes that remove the default axis lines and use formatted tick labels (abbreviating millions with "B"). The chart is built with React and rendered as SVG, using D3 v5 APIs including `scaleLinear`, `scaleBand`, `axisBottom`, `axisLeft`, and `format`. Population data is loaded from a CSV file and multiplied by 1000, with grid lines generated via negative tick sizes and axis titles added as text elements.
