This visualization displays line charts of confirmed COVID-19 cases over time for multiple countries, with each country represented by a distinct colored line. The chart uses d3.csv to load data from a GitHub repository, d3.scaleTime and d3.scaleLinear for axis scaling, and d3.line to generate the paths. An ordinal color scale assigns unique colors to each country, while d3.axisBottom and d3.axisLeft render the time and case count axes in an SVG canvas.
