This stylized bar chart displays UN population data for the top 10 countries, using horizontal bars colored by a custom `selectColor` function that randomly assigns hues from a fixed palette. The React front-end leverages D3 v5’s `scaleBand` and `scaleLinear` for axes and layout, with `AxisBottom` and `AxisLeft` custom components rendering SVG ticks. Data is loaded asynchronously from a CSV via `useData`, and tooltips using D3’s `format` provide formatted population values on hover.
