Automation is an area of pretty active development. While visual workflows aren't a thing in HA, you definitely don't need to write yaml in order to create automations. The UI has supported it for quite some time (and is quite usable, in my opinion).
There's some NLP involved since the latest version got released (0.102), so you can just type some simple automation like "turn off lights when I leave home".
