Built with D3 v5, the visualization employs `scaleTime`, `scaleLinear`, `d3.area` with `curveBasis`, and `axisBottom`/`axisLeft` for axes, all rendered as SVG. CSS styles the path and text, while data comes from a CSV file parsed with `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ba73e77a8c149e2b38ef62db159b18c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
