{"version":"1.0","type":"rich","title":"Question2_Answer2","description":"This example displays a green area chart of United States population from 1995 to 2020, with years on the x-axis and population on the y-axis. The visualization filters a CSV dataset for the United States and maps yearly values using `d3.scaleBand` and `d3.scaleLinear`, then renders the area shape with the `d3.area` function. Axes are drawn using `d3.axisBottom` and `d3.axisLeft`, with rotated year labels and manually added title and axis text. The result is rendered as an SVG element with a width of 900 and height of 450 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/327ee83b326f4b98b8bb75f14f51a0b9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
