A line chart displays the annual GDP of Serbia over time, loaded from a CSV file and rendered as a smooth natural curve. The visualization uses React to build SVG elements, with Axes and Marks components, while d3.scaleTime and d3.scaleLinear handle the x- and y-axis scaling. Tooltips are included as commented-out code, and the chart applies a Poppins font with a custom color scheme for the line and axes.
