{"version":"1.0","type":"rich","title":"Fork of test","description":"This area chart visualizes population trends over time for multiple countries, using filled paths to compare growth patterns across categories. Built with D3 v6, the code loads CSV data from a GitHub gist, processes it into time-series values, and renders axes and colored areas via `d3.area` and `d3.curveMonotoneX`. A categorical color scale and legend identify each country, while the chart is generated as SVG with custom margin and sizing options.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e79da3bccf2c4e548eef03806bf04b12?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
