{"version":"1.0","type":"rich","title":"World population area chart","description":"This area chart visualizes global population trends over time using a smooth, filled curve. The chart loads data from a CSV file containing annual world population estimates, which is parsed and mapped onto time and linear population scales. D3's `area` and `curveBasis` APIs generate the smoothed area path, while `axisBottom` and `axisLeft` construct the axes with custom tick formatting. The visualization also includes axis labels and a title, rendered as SVG elements within a 960x500 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c956cc7be8b450bb2a16e63b5187901?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
