{"version":"1.0","type":"rich","title":"Fork of Melting Data for Multiple Lines","description":"This example visualizes population over time by region, displaying multiple lines that trend across a time axis with a categorical color legend. It uses D3 v5 APIs including `d3.nest`, `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and `d3.axisBottom` to render an SVG chart. Data is melted from UN population estimates and medium-variant projections, combining CSV sources. A custom color legend module and `mix-blend-mode` styling enhance readability, while axis labels and tick formatting clarify the scales.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ec5771c98c04ab5999615fe4a3d0d7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
