The chart is rendered as SVG using D3 v5, employing `d3.csv` to load the data, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.line` with `curveBasis` for the smoothed path. Axis labels, tick styling, and a title are applied via D3 selections, while the dataset originates from a CSV file hosted on VizHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60b381c816d64883b06ee4aaedc7f47f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
