Usakana I see, thanks for claryfing. So why not use a path attachment to draw a line that indicates the path?
Some Spine users have interesting ideas, and some even use bones to write the limits of how far a bone can be moved, like the following image:
The bones surrounding the bone named Controller are placed to tell the animator the limits of what the Controller can move. Those bones are not used to actually move the character. The placement of these useless bones has almost no effect on performance.
If you uncheck Select in the bone's properties, you will not accidentally it in the viewport:
The path attachment also has the Select property and can be excluded from the skeleton data to be exported by unchecking Export.
Although a slightly different approach, it is possible to use bones and path attachments in this way to illustrate something.
You may have already thought of these, but I hope they are helpful to you.
