{"version":"1.0","type":"rich","title":"Melting Data for multiple lines","description":"This visualization shows world population estimates for different regions over time as multiple colored lines. It uses a line chart with an ordinal color scale to distinguish each region. The example loads data from CSV files, nests it by region using `d3.nest`, and renders smooth curves with `d3.line` and `curveBasis`. It also includes a custom color legend component and styled axes with grid lines.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f487d196fab4dca9072837fd5f98dba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
