The links between products on this page are a placeholder, made up close to random, to show how the network will look. The dependency data that will replace them is still to come.
Each heading’s links are inferred from its products’ links: the links between the products of two headings, added up and divided by the square root of the product of how many products each holds, so a heading with many products is not tied to everything only because it has more products to link from. Heading names are the phrase most of their products’ descriptions open with.
