The demo works well and is a good representation of echoSMs.
One minor issue is that when I use the command to plot the cod fish body and swimbladder outlines (echosms.KRMdata().model('Cod').plot()), the snout of the fish is at ~400 mm instead of at 0 mm - i.e., both the swimbladder and fish body are flipped horizontally (it's good that both are flipped rather than only one). I think we should keep the convention that 0 is the furthest anterior point of the digital data. I think I saw a plot generated by you where the snout was at 0, so I wonder if the coordinate system of the plot needs to be defined?

I noticed yesterday that the KRM shapes were not following the echoSMs coordinate system convention (head was towards -ve x direction instead of +x) so I flipped the data (new_x = max(old_x) - old_x). Adding the convention of having the furtherest anterior point at x=0 means that the rest of the body will have negative x coordinates - a minor inconvenience. Or for plotting we can invert the x-axis but this has the side effect of changing which side of the organism is facing the viewer.
