It uses an SVG line chart with a time-scaled x-axis and a linear y-axis, rendered with D3.js v6 in a React framework. The code filters and aggregates data from a CSV source, assigns distinct colors to each country, and includes gridlines, a title, and a legend. The visualization supports animation, though the provided code focuses on static line rendering with interactive color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03a3b6fa3615436a91bd22aa5e3ac127?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
