This example visualizes vehicle flow counts across six categories (labeled 0–5) using a horizontal bar chart, with bars right-aligned and colored green. The chart is rendered as an SVG via D3 v6 within a React framework, using `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis. Both axes are positioned on the right and bottom edges, with axis labels and tick text styled for readability. The data is hard-coded in the script, and the layout includes margins and a main group for organized rendering.
