{"version":"1.0","type":"rich","title":"1115南进口道堆叠图","description":"This visualization shows a stacked bar chart of traffic counts across six lane positions on a southbound approach, broken down by traveler type: pedestrians, non-motorized vehicles, and motor vehicles. The data is hardcoded in the script. It uses D3 v6’s `d3.stack()` and `d3.scaleBand()` to arrange the categorical lanes, with `d3.scaleLinear()` mapping the stacked heights. Color is assigned via `d3.scaleOrdinal()` with `d3.schemeSet3`, and the SVG renders the bars, axes, and a custom HTML legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e066f10585741fe80372458c1c6383a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
