A horizontal bar chart displays the vehicle flow values for six time intervals (0 through 5) at the "1114西进口道机动车" intersection, using green bars with an opacity of 0.8. The SVG rendering is built with D3 v6, employing `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and `d3.axisLeft`/`d3.axisBottom` to generate axes. The hardcoded dataset includes values from 18 to 80.
