I understand very little of what any of this data means, but I am quite proud of how readable the graph is. (with the exception of details like the freq axis ticks...)

In general, it is very hard to interpret a single line in 3D from just a static plot. Even with the 3 projections onto the 3 "walls", it's not easy to intuitively understand the shape of the line and how it behaves.

The regularly spaced vertical lines together with the semi-transparent fill make it surprisingly easy to just understand the shape, simply from looking at it. And basically from any direction.

There aren't too many real-life cases where you have a single line in a 3D space, but I'm definitely going to use this exact visualisation again if I ever come across one!
