{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines","description":"This example visualizes COVID-19 death counts over time for seven countries, with each country represented as a colored line and labeled at its final data point. The chart uses a linear time scale for days since the 10th death and a linear scale for death counts, with axes and a color legend rendered by custom D3 functions. The code loads CSV data, processes it, and uses `d3.nest` to group by country, `d3.line` with `curveBasis` for smooth paths, and `d3.scaleOrdinal` for colors. The visualization is rendered as SVG with D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
