The data is loaded from a CSV file and rendered as an SVG using D3 v5. The code employs `d3.scaleTime`, `d3.scaleLinear`, and `d3.area` with a basis curve to draw the shaded region, while `d3.axisBottom` and `d3.axisLeft` provide labeled axes with formatted tick values. The chart includes a title and axis labels styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e85e39f4ae5d448eaacba9dba4295420?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
