Fork of Zadluženost států Pie chart
A pie chart depicts the national debt of thirteen countries as a proportion of their GDP, using a diverging color scale from yellow to red. Built with D3 v6, the visualization employs `d3.pie()` to compute arc angles, `d3.arc()` to generate SVG paths, and `d3.scaleOrdinal()` with an interpolated color range. Labels are positioned using arc centroids via `d3.arc().centroid()`. Data is loaded from a local CSV file.
