It renders an SVG multi-line chart, with each pollutant line colored by a categorical scale and labeled near its final data point. The code loads data from a local CSV, parses dates with `d3.timeParse`, and generates paths with `d3.line`. Axes are added using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1a7563da25f242a2ac012318f6ce1487?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
