{"version":"1.0","type":"rich","title":"Worldwide Population","description":"This visualization presents global population growth from 1950 to 2015 using two complementary SVG charts: a line chart and an area chart, both rendered with D3 v5. The data from a CSV file is mapped with `scaleTime` for the temporal x-axis and `scaleLinear` for the population y-axis, with tick values formatted to show billions. Both charts share axes and margins, but the line chart uses a single red, semi-transparent path via `d3.line` and `curveBasis`, while the area chart fills the space beneath its curve using `d3.area`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af1a4818f33f491abf2cb6d962f7bd94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
