This example shows horizontal bar charts for the populations of five cities, with city names positioned to the right of each bar. A hover effect changes the bar color from steelblue to orange. The visualization is built with D3 v7, using selections, data binding, and the `join` method to create SVG `rect` and `text` elements. The data is hard-coded in an array of city objects, and bar widths are scaled by multiplying population values by a constant factor.
