This example creates a horizontal bar chart where each bar's length corresponds to its numeric value. The visualization is rendered as a block-level `<div>` element, with individual bars styled using steel blue backgrounds and inline widths proportional to the data. The code uses the D3.js version 6 API, specifically `d3.create`, `selectAll` with a `data` binding, and the `.join` method to append new elements. Each bar displays its value as white, right-aligned text within a 10-pixel sans-serif font.
