{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines","description":"This visualization uses D3.js (v5) to animate the growth of confirmed COVID-19 cases across multiple countries, displaying them as a series of colored lines on a scatter plot. The lines are drawn using `d3.line` with `curveBasis` smoothing, and each country is distinguished by color from `d3.schemeCategory10`. The animation progresses through time by updating the data on a timer, redrawing the line paths with `transition().duration(1000)`, and the labels and circles animate to track the latest values. Data is processed from CSV files, where the code melts the data from a wide format into a long format for plotting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
