{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart visualizes world population by year up to 2015, using a smooth curve filled in maroon. The x-axis maps time via `d3.scaleTime`, while the y-axis uses `d3.scaleLinear` with tick formatting that abbreviates billions. Data is loaded from a CSV using `d3.csv`, and the path is generated with `d3.area()` and `curveBasis`. Axes and labels are built with `d3.axisBottom` and `d3.axisLeft`, rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6d7cee85522741b9a2ff769d20596aab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
