{"version":"1.0","type":"rich","title":"World Population Area chart","description":"This area chart visualizes world population by year using a dataset from VizHub’s world-population-by-year-2015 CSV. It renders an SVG with D3 v5, using `scaleTime` and `scaleLinear` to map years and population values, and `d3.area()` with `curveBasis` to draw the smoothed filled region. Axes are generated via `axisBottom` and `axisLeft`, with tick labels formatted to abbreviate billions as \"B\". The chart includes axis labels and a title, all styled via external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27282936bdc94d6e9832da86bdca32a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
