{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines 2","description":"This visualization shows population trends over time, displaying multiple lines for different regions as determined by the United Nations data. The chart uses a time series layout, with a legend positioned on the right, created using D3’s `scaleOrdinal`, `scaleTime`, and `scaleLinear`. Lines are drawn with the `line` generator, using the `curveBasis` option for smoothness, and are sorted by their last value via `d3.nest`. Data is melted from a CSV file (`us-unemp.csv`) using custom parsing, with `timeParse` converting year strings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6998dc58159343c9bdca7014fb969137?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
