I also had this feeling that my entire approach causes too much work, because I don’t prepare the data well enough. Ultimately, I know the time of the events, and I know the exact distance I want between any two events. This is pretty solid information that is not directly translated into useful constraints for dot to use (I believe). As long as the output was generated quickly, and the result looked right, I didn’t care that my approach might not be ideal. But I was wondering if it could be beneficial to try to use neato guided by pre-calculated pos attributes. Just another thing for me to evaluate though.
