The visualization uses D3.js version 5, with the `d3.area` generator and `d3.curveBasis` for the smoothed path, along with `d3.scaleTime` and `d3.scaleLinear` for the axes. The chart is rendered as an SVG, with gridlines and axis labels styled via CSS. Population data is loaded from a CSV file hosted on VizHub, formatted with a custom tick formatter that converts billions to \"B\".","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4e85fba025249bc9c7e79eb2cd0b237?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
