{"version":"1.0","type":"rich","title":"Bar Chart Learning","description":"This area chart visualizes world population trends over time, using a smoothed curve to show the growth from 1950 to 2015. The y-axis is labeled with a custom formatting function that converts tick marks to billions. Built with D3 v6, the visualization employs `scaleTime` for the temporal x-axis, `scaleLinear` for the population y-axis, and the `area` generator with `curveBasis` to create the filled path. Data is loaded from a CSV file hosted on Vizhub, sourced from the UN World Population Prospects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c9005a8a3fe4191baceaf3b1dee0cd5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
