{"version":"1.0","type":"rich","title":"World Population — Area Chart","description":"This area chart visualizes world population growth from 1950 onward, with the x-axis representing years and the y-axis showing population counts in billions. The chart uses a smooth curve (via `curveBasis`) to connect data points, creating a filled area rendered in green. Population data is loaded from a CSV file and parsed with D3’s `csv` function, while the visualization leverages D3 v5 components like `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`. The SVG output includes labeled axes, a title, and a dashed grid, all styled with custom CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ccd116248784184a4bce97a0d6f28e2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
