{"version":"1.0","type":"rich","title":"1120所有堆叠图（右转-过街）","description":"This stacked bar chart visualizes traffic flow across 27 lanes at an intersection, showing counts of pedestrians, non-motorized vehicles, and motor vehicles. The SVG rendering uses `d3.stack()` to create stacked segments for each lane category, with `d3.scaleBand` positioning the bars and `d3.scaleOrdinal` assigning colors from `schemeSet3`. A tooltip appears on mouseover, displaying the percentage each category contributes to the lane’s total. The data is embedded directly in the code, and the visualization includes axis labels and a custom legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/24a1511693ec45b1bac2b5fdca90fe30?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
