{"version":"1.0","type":"rich","title":"Areachart_Question-2","description":"This area chart visualizes the world population from 1950 to 2015, sourced from the United Nations World Population Prospects 2017. The chart uses a smooth, curved area path to show population growth over time, with a red filled region and orange data points. The visualization is built with d3.v5, using `scaleTime` and `scaleLinear` for the axes, `area` with `curveBasis` for the area path, and `axisBottom` and `axisLeft` for the labeled axes. It also includes a custom tick format that converts values to billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fd039058a91b476fbd3cb7367435a92b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
