{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart visualizes world population growth from 1960 to 2015, with a maroon filled region under a smoothed curve. The x-axis shows time, while the y-axis displays population counts formatted in billions. Built with D3 v5, the visualization uses `d3.area()` with `curveBasis` for the smooth path, `d3.scaleTime` and `d3.scaleLinear` for scales, and `d3.axisBottom` and `d3.axisLeft` with gridlines. Data is loaded from a CSV file via `d3.csv`, and the SVG rendering includes custom axis labels and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a2d72b4ddc544589feb6de0e6f784ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
