{"version":"1.0","type":"rich","title":"World Population Area Chart","description":"This visualization presents global population trends from 1950 to 2015 as a filled area chart, with the vertical axis representing population in billions and the horizontal axis showing time. The chart uses D3 v5’s `area` generator with `curveBasis` smoothing, paired with `scaleTime` and `scaleLinear` for axes. Data comes from the UN World Population Prospects 2017, loaded via `csv` and rendered into an SVG. Axis labels and ticks are styled with custom formatting, and the area fill is maroon.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/183fdeaf9fc94f96adb12e0ff8aa1d28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
