{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines","description":"This visualization depicts the cumulative number of COVID-19 deaths across various countries, plotted against the number of days since each country recorded its tenth death. The chart uses multiple lines, color-coded by country, with a legend to identify each one. The data is processed from CSV files, and the visualization is built with D3 v5, using scales like `scaleLinear`, axis functions, and the `line` generator to create the paths. The code also includes custom logic for data cleaning and merging the datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff196cd1b6d642b99cfc2ae8cc234299?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
