{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart displays the population of the USA from 1960 to 2021, with time on the x-axis and population count on the y-axis. The visualization uses D3 v5 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`. It generates a line path via `d3.line` and fills the area beneath it using `d3.area` with `d3.curveBasis` smoothing. The data comes from a CSV file loaded with `d3.csv`, and axis labels are added directly in the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a57189fc2ed4861a12e80572fdd7e35?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
