{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines","description":"This example visualizes population trends for multiple countries over time as a series of colored lines, using a legend to identify each country. The chart displays time on the x-axis and population on the y-axis, with a title and axis labels. The code uses `d3.csv` to load data from a UN population estimates dataset, which is then \"melted\" from wide to long format to create individual line paths. It leverages D3 v6 APIs including `scaleTime`, `scaleLinear`, `scaleOrdinal`, `line`, `curveBasis`, `axisLeft`, `axisBottom`, and `group`, rendering the final visualization as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e25478a3d0c14b8cb89bebd71d04b6c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
