{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart visualizes world population growth from 1800 through 2015, using a filled path to emphasize the magnitude of increase over time. The chart employs `d3.area()` with a `curveBasis` smoothing, while `d3.scaleTime` and `d3.scaleLinear` handle the axes. Data loads from a CSV via `d3.csv`, with SVG rendering and custom axis formatting that converts billions to \"B\" labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2156393210434366b179da7dd43a1b29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
