{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart displays global population growth from 1915 to 2015, with a purple area curve and semi-transparent circles marking each year’s data point. Built with React and D3 v5, it uses `scaleTime` and `scaleLinear` for axes, an `area` generator with `curveBasis` for the smoothed path, and `axisBottom`/`axisLeft` with custom tick formatting. Data is loaded via D3’s `csv` from a VizHub dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/910564ce871941aaa8e5f54f077392ad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
