{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This area chart visualizes world population from 1950 to 2015 using a smooth, filled curve. The chart highlights population growth over time, with a maroon area beneath the line and labeled axes for year and population count. Built with D3 v6, it uses `d3.csv`, `scaleTime`, `scaleLinear`, `area` with `curveBasis`, and `axisBottom`/`axisLeft` to render an SVG. Data comes from the UN World Population Prospects 2017 dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/724484be06be4bdc825d49891e3e9955?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
