The SVG rendering uses d3.stack to create the layered segments, with d3.scaleBand for lane positioning, d3.scaleLinear for the y-axis, and d3.scaleOrdinal with the schemeSet3 color palette. Each lane’s stacked segments show the proportional counts of three transportation modes, using d3.axisLeft and d3.axisBottom to display the scales.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6854c400ea254980a73941c6d470bb63?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
