{"version":"1.0","type":"rich","title":"Fork of Melting Data for Multiple Lines Rogery","description":"This example shows population trends over time for world regions, with multiple lines plotted on a shared time axis and colored by region. The chart uses a legend to identify regions, with lines sorted by their final population value. It loads data from UN population estimates CSV files, processes it with a custom melt function, and renders using D3 v5 with SVG. Key APIs include d3.line, d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.nest, and d3.axisBottom.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/04eead8b33a541d2be8e0fe3234e2f26?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
