The React-based chart uses d3.scaleTime and d3.scaleLinear to map dates and percentages, while d3.line with curveNatural renders the smooth path. Each data point is marked with an SVG circle that includes a hover tooltip via the title element, and axes are generated using custom React components that leverage d3's scale ticks for positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e56eff6b53ed4aaabf110c742fb9ed81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
