{"version":"1.0","type":"rich","title":"Untitled","description":"This example displays a world population area chart over time, using a maroon filled path with a smooth curve to emphasize the data’s upward trend. The SVG rendering relies on D3 v5’s `area`, `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` APIs, with data loaded from a CSV file. The y-axis labels are formatted in billions, and the x-axis labels are rotated vertically for readability, alongside custom tick grids and a descriptive title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1019fe0d49e4f45ac7d5c05db5e28b5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
