It seems like there's no way to just symbolise the line as a zigzag: unfortunately, you'll have to alter the underlying data. You can get a reasonably good zigzag line by first splitting the original line into many equidistant line segments, and then offsetting every other point by a fixed amount. Here's a Python script that does this, taking NathanW's ...

I've tried to do this before and haven't had much luck. qGIS places repeated symbols on a line based on one reference point (by default, the center, though you can set it to top/middle/bottom x left/center/right), and rotates that symbol based on the slope of the line at that point. On a straight line, where the slope doesn't change from one symbol ...

One of the layers with a slightly larger scale and one with a slightly smaller scale. Densify the geometry of the layers. That means add more nodes. Go to the attribute table and name each feature node consequently ...

Credit for pointing this out goes to @FranceImage. You can't use the L.circleMarker layer with the spiderfier plugin, it will ...
