The x-axis maps years using `d3.scaleTime`, while the y-axis uses `d3.scaleLinear` with a tick format via `d3.format`. The chart is rendered as an SVG using `d3.area` and `d3.line` with `d3.curveBasis`, and data is loaded asynchronously from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b78de74546cd48d6997d3fae27d02ef3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
