It is known that the straight skeleton of a simple polygon is a tree, and one can naturally derive directions on the edges of the tree from the propagation of the shrinking process. In this paper, we ask the reverse question: Given a tree with directed edges, can it be the straight skeleton of a polygon? And if so, can we find a suitable simple polygon? We answer these questions for all directed trees where the order of edges around each node is fixed."}],"doi":"10.1007/978-3-319-27261-0_28","publication_status":"published","publication":"Graph Drawing and Network Visualization","publisher":"Springer Nature","alternative_title":["LNCS"],"conference":{"name":"GD: International Symposium on Graph Drawing","start_date":"2015-09-24","end_date":"2015-09-26","location":"Los Angeles, CA, United States"},"date_created":"2018-12-11T11:52:54Z","status":"public"},{"date_updated":"2022-01-28T09:20:50Z","has_accepted_license":"1","project":[{"grant_number":"291734","name":"International IST Postdoc Fellowship Programme","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"publist_id":"5575","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","department":[{"_id":"UlWa"}],"language":[{"iso":"eng"}],"_id":"1596","year":"2015","date_published":"2015-11-27T00:00:00Z","type":"book_chapter","article_processing_charge":"No","citation":{"ieee":"R.
