cargo depgraph [options] | dot -Tpng > graph.png

The full list of options can be seen by running

cargo depgraph --help

Commonly useful options:

cargo-depgraph's dependency graph

cargo-depgraph's dependency graph with transitive dependency edges de-duplicated

square node = root / workspace member
grey background = target-specific dependency
dotted lines = optional dependency (could be removed by disabling a cargo feature)
dashed lines = transitively optional dependency (could be removed by removing one of the dotted edges)
line colors = dependency kinds w.r.t. root / workspace members
- black = normal
- blue = dev-dependency
- green = build-dependency
- light turquoise = build-dependency of a dev-dependency
- dark green = both normal and build-dependency
- violet = both dev-dependency and build-dependency
- … not seen in the wild yet, but theoretically possible:
- dark turquoise = both normal and build-dependency of a dev-dependency
- pastel blue = both dev-dependency and build-dependency of a dev-dependency
- red = you broke it
