{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This visualization displays the cumulative COVID-19 case counts for the top 10 countries from January to July 2020, using multiple animated line paths over a time-based x-axis and a linear y-axis. Each country’s line is color-coded via a d3.scaleOrdinal with a category scheme, and a legend is rendered with d3’s select/enter/merge pattern. The lines animate using `transition.attrTween`-like path drawing with `stroke-dasharray` and `stroke-dashoffset`, while axes are built with d3.axisBottom and d3.axisLeft. Data comes from a CSV file, loaded without visible d3.csv (assumed external).","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0d0d6067653b45c0acc39c250e1fc539?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
