This example demonstrates a network visualization with nodes representing servers and proxies, linked by connections labeled with ports and protocols. Animated SVG paths show link directions, while each node displays a Font Awesome icon based on its role via `d3.select`. The code uses `d3.linkVertical()` to draw curved paths from hard-coded `x` and `y` coordinates, with tooltips and color-coded elements defined in the stylesheet. The network data is static, defined explicitly in the JavaScript, and rendered using D3 v6 in an SVG container.
