# Step 9: Dep Graph

An Nx workspace can contain dozens or hundreds of applications and libraries. As a codebase grows, it can be difficult to understand how they depend on each other and the implications of making a particular change.

Previously, some senior architect would create an ad-hoc dependency diagram and upload it to a corporate wiki. The diagram is not correct even on Day 1 and gets more and more out of sync with every passing day.

With Nx, you can do better than that.

!!!!!
Run "npm run dep-graph". What do you see?
!!!!!
A dependency diagram in the browser
A dep-graph.html file created at the root of the workspace
A json document printed out in the terminal
