{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines","description":"This visualization animates the growth of COVID-19 confirmed cases across multiple countries, using stacked line paths that extend day-by-day. The y-axis applies a random multiplier to China’s data after day 52, creating a visual distortion. Built with D3 v5, it uses `scaleLinear`, `nest`, and `line` with `curveBasis` to generate smooth trajectories, while `transition` animates the lines. Country labels and color-coded legends are rendered as SVG text and circles, with data sourced from CSV files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e44d356dc49545efa9658f9cdcd3338a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
