{"version":"1.0","type":"rich","title":"Final Project- Multiple line chart ","description":"This visualization shows GDP per capita trends from 2019 to 2023 for five selected countries: the United States, India, Germany, Brazil, and China. The chart displays five polylines, one per country, with distinct colors and a legend identifying each line. The SVG rendering uses `d3.line()` to generate the paths and `d3.scalePoint()` for the x-axis years, while `d3.legendColor()` creates the color legend. Data is loaded from a CSV file via `d3.csv()` and processed into long format for plotting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49ec92f54b334bb08f45cf17c5783dd7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
