getGraph example

// If checking content, module, or theme dependencies, discover which       // entities are dependent on the entities that have a direct dependency.       foreach ($dependent_entities as $entity) {

      }
    }
    $dependencies = array_merge($this->createGraphConfigEntityDependencies($entities_to_check), $dependent_entities);
    // Sort dependencies in the reverse order of the graph. So the least     // dependent is at the top. For example, this ensures that fields are     // always after field storages. This is because field storages need to be     // created before a field.     $graph = $this->getGraph();
    $sorts = $this->prepareMultisort($graph, ['weight', 'name']);
