{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart visualizes the cumulative and daily COVID-19 case counts for ten countries up to July 28, with buttons to toggle between total and daily cases. Lines are drawn with an animated stroke-dashoffset transition using D3’s `transition()` method, and SVG paths are generated via `d3.line()`. The chart includes a color legend mapping countries to a categorical scheme, axis labels, and annotations marking notable events. Data is loaded from a CSV file, and the visualization is built with React and D3 v5, rendered as SVG with animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c29d0b42bd7848958cf33892b204fada?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
