This chart displays the GDP of Serbia, Slovenia, Croatia, and Romania from 1995 to 2019, using overlapping thick lines to trace each country’s economic trajectory over time. The visualization relies on React for structure and D3 v6’s `scaleTime`, `scaleLinear`, and `scaleOrdinal` to map years, GDP values, and country colors onto an SVG canvas. Data is loaded from a CSV file via D3’s `csv` function, with axes rendered as custom components and line paths generated using D3’s `line` generator.
