{"version":"1.0","type":"rich","title":"World population area chart","description":"This visualization displays global population growth over time as a filled area chart, with the area beneath the line shaded maroon to emphasize the total population magnitude. The chart uses D3 v5’s `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to smooth the curve, along with `axisBottom` and `axisLeft` for labeled axes. Data is loaded via `d3.csv` from a VizHub dataset, and the y-axis labels are formatted to abbreviate billions. A title and axis labels are added via SVG text elements, with styling applied through the included stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b55b95cfff6148c6a85f3371fcc8ef14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
