This example shows traffic flow at the north entrance of road 1115, with six categories labeled 0 through 5 and their corresponding vehicle counts (ranging from 1 to 44). Green bars represent each value, with the chart oriented so bars extend rightward from the y-axis. The visualization uses D3 v6 with SVG rendering, employing `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `axisTop` and `axisRight` to display axes. Text labels are enlarged using D3 selections, and a custom "车流量" (traffic flow) title is added.
