This example displays a bar chart of vehicle counts across six time intervals, labeled 0 through 5, for the "1115南进口道" (south entrance road). The green bars, rendered via D3’s `scaleBand` and `scaleLinear`, show counts ranging from 1 to 56. The chart uses D3 v6’s `axisBottom` and `axisLeft` to generate axes, with all tick labels enlarged to 2em. The SVG is created directly in HTML, with the main chart group offset by margins, and includes a text label for “车流量” (traffic flow).
