Well thought out node graphs designed with proper color coded backdrops are not only a pleasure to pick up and work with but also a sight to admire when you step back and appreciate all the hard work you've put into your comp.
I highly encourage all junior artists to establish this good habit early on as it will save you loads of time in the long term just from being able to quickly glance through and diagnose your scripts.
Also, who doesn't like node graph porn?
