This chart displays the change in GDP per capita for Afghanistan over time during the COVID-19 pandemic. A black line traces the trend, with the date on the x-axis and the GDP per capita value on the y-axis. The visualization is built with D3 v5, using `d3.scaleTime` and `d3.scaleLinear` for the axes, `d3.line` for the path, and `d3.csv` to load the remote data. The SVG output includes labeled axes and a grid, with the line path styled through the `line_path` class.
