Layering

of imports point one way

From the map of which files import which. It shows what depends on what, not a reading order.

Module map

Shade by

3 modules, 0 links. A link means one module imports another; thicker lines mean more imports. Links come from 400 of 6,374 source files, so the real counts are higher. Select a module to trace it: blue lines go to what it uses, orange lines come from what uses it.
