Face with D3
This example uses D3 to render a face constructed from stylized line segments, with the entire drawing output as SVG. The visualization relies on D3’s force simulation to position the facial features dynamically, while the CSS defines thick, round-joined strokes with a purple color for the lines. The face emerges from the coordinated placement of paths within a fixed 960×500 SVG canvas, showing how D3 can drive both layout and rendering. The code uses `d3.forceSimulation` to compute the arrangement of elements, and the SVG paths are styled via the `.lines` class.
