This example shows a static sankey diagram with three sources flowing into two servers and then to two analysts. Each link has an equal value of ten, and the diagram uses a simple, uncolored visual style with black strokes and opacity. The code builds the visualization using the `d3.sankey` extension, defining nodes and links as data, and renders it as an SVG. It manually sets the node width and padding, and uses a custom color function for node fills, though colors are not defined in the visible snippet.
