flagtrafo was developed by Lukas D. Sauer at the Heidelberg Institute of Theoretical Studies in 2019, under the supervision of Anna Wienhard. A special thanks goes to Sven Grützmacher: His Master's thesis code contributed to the library projflag-lib, which is used for the server-side calculations of the flag complexes.

This application was designed using Flask, nginx, Milligram.css and D3.js.
