This example shows a horizontal bar chart of population counts for East Japan’s most populous prefectures, with custom-styled axes for readability. It loads CSV data using `d3.csv`, scales populations with `d3.scaleLinear` and prefectures with `d3.scaleBand`, and renders bars as SVG `rect` elements. The axes are built with `d3.axisLeft` and `d3.axisBottom`, using `d3.format` for compact number labels and custom tick sizes and gridlines. Axis labels and titles are added manually, with the default domain lines removed for a cleaner design.
