The chart employs D3 v5’s `scaleTime` and `scaleLinear` for axes, with `area()` and `line()` generators using `curveBasis` for smoothing. Axis labels and tick text are styled via CSS, and data is loaded from a CSV hosted on GitHub Gist.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e91204b435704f7dace98dc74b4abe95?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
