Agreed. This is a good library but it is let down by lack of documentation. Reading the source doesn't help, e.g. this is "explaining" the parameters in the plot function:
# Whether to use a backup for the layers
backup = None,
# Custom postprocessing function on layers
postprocessing = None,
# Radius (in case of circular plot)
radius = None,
These sorts of comments merely repeat what's in the code and are worse than useless.
I was hoping for some more documentation apart from the usage examples, although those are much appreciated too.
