{"version":"1.0","type":"rich","title":"World Pop Areachart","description":"This areachart displays global population growth over time, using a filled path to emphasize the rising trend from historical data to 2015. The visualization loads a CSV dataset, parses years as dates, and renders an SVG using D3 v5's `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to create a smooth, filled curve. Axis grids and labels are generated with `axisBottom` and `axisLeft`, while population values are formatted with abbreviations like “B” for billions. The title and axis annotations are drawn directly on the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b39b63e46504cf2812f371374c51347?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
