{"version":"1.0","type":"rich","title":"Area chart","description":"This area chart visualizes world population growth over time, using a smooth filled curve to show the increasing trend. The chart is rendered with D3 v5 in SVG, pulling data from a CSV file of world population by year. The code uses `d3.area()` with a basis curve to generate the path, while `d3.scaleTime` and `d3.scaleLinear` handle the axes. Axis labels and a title are added via SVG text elements, with tick formatting that converts large population values to billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f13f983fcd3420b894673b26e6df94f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
