In our discovery sessions we had 2 types of views that wanted to be shown in the UI: Time view and relation view. because we work in a 2D surface (the monitor), we needed to sacrifice one or the other. From there we had to decide what direction we wanted to go. While option 1 (image on the left) had less effort to build because it used similar components, it had a number of restrains that would have brought new problems to the table. So we opted to go with option 2 (image on the right) and use time as our main point of view.
