Hello Matteo, I am currently working on a quiz app and would like to visualise the flow of questions and answers in the quiz. The flow is basically a directed acyclic graph and while researching for a suitable visualization form I came across your impressive "Tangled tree visualization" notebook. I have tried several graph layouts, but "Tangled trees" is by far the best visualisation. My question is, is the code from the notebook free to use, e.g. in an app, or is there any licence or attribution requirement? Many thanks and best regards, André

Hello André, this notebook is now placed under an MIT license, so you are free to use the code for your app. You just need to include the license as well as an attribution line in your codebase. Thanks for reaching out to me, Matteo

Hello Matteo, wonderful, I will do that! And thank you so much for taking the time to clarify the question. Your Tangled Tree visualization is a great open source contribution. Many greetings, André
