Of note in this hypothetical example:
views_data_export, has been added directly by the site.pantheon_saml_auth, utevent, utnews, and utprof, have also been added directly by the site.
utexas/upstream-configuration dependency is a local repository that contains the UT Drupal Kit kernel. Within that, utexas/utdk_profile defines the dependency to Drupal core, along with a variety of contributed modules.Click the colored nodes to expand their dependencies.
