It uses D3 v5 with nested data grouping via `d3.nest()` and renders SVG paths generated by `d3.line()` with a basis curve. The chart includes axes from `d3.axisBottom` and `d3.axisLeft`, and a custom color legend built with `scaleOrdinal` and `schemeCategory10`. Data comes from the Data Canvas - Sense Your City dataset, loaded as CSV.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/64d73ea206c64f2899afb03a48757ca9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
