The chart uses d3.scaleTime for the x-axis and d3.scaleLinear for the y-axis, with data loaded via d3.csv from a GitHub gist. d3.line and d3.area generators apply curveBasis to create the smoothed paths, while d3.axisBottom and d3.axisLeft add labeled axes with a rotated y-axis title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca655300cf3440edb2aa3838863f0149?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
