{"version":"1.0","type":"rich","title":"1116西北crosswalk堆叠图","description":"This visualization displays a stacked bar chart of traffic counts for a single crosswalk lane, breaking down volumes into pedestrians, non-motorized vehicles, and motor vehicles. The single bar shows 119 pedestrians, 17 non-motorized vehicles, and 0 motor vehicles, with stacked segments colored via d3.schemeSet3. Built with D3 v6 and rendered as SVG, the code uses d3.stack(), d3.scaleBand(), d3.scaleLinear(), and d3.axisLeft/axisBottom to construct the chart. A separate HTML legend is generated using D3 selections with colored swatches. The example appears to derive from a crosswalk traffic study dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3d66e9640f9429ca7c1b61427a9412e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
