This multi-line chart displays military spending trends from 2001 to 2020 across eight countries, with the y-axis showing spending amounts and the x-axis representing years. The visualization uses D3 v5 to render an SVG, applying `scaleLinear` for both axes, `line` with `curveBasis` for the path, and `nest` to group data by country. The chart includes axis labels, a title, and a single maroon line path, though the nested data structure is logged but not separately rendered as distinct lines.
