A circular dependency is an issue that we can encounter when working with multiple components and dependencies. Sometimes it is possible to reach a point in which one component (A) has a dependency on a second component (B), which depends on the first component (A).

The nodes without dependencies are displayed in green, and those with dependencies but no issues are displayed in blue:
The circular dependencies don't necessarily need to involve just two components. We can ...
