Three pie charts show the distribution of Protestant, Roman Catholic, and other religious populations across total, urban, and rural areas of Germany in 2014. Using D3.js version 3.5.5, the visualization employs `d3.layout.pie` and `d3.svg.arc` to generate the slices, with `d3.scale.ordinal` positioning each chart along a shared x-axis. A categorical color scale and a D3 legend component distinguish the religions, while data from UN Data is loaded from a CSV file. The SVG rendering includes custom axes and labels.
