Run and visualise methods in ManifoldLearning.jl

Hello,

I am using the package ManifoldLearning.jl

Can anyone help me get these methods (except LEM and LTSA) running, it seems they’re broken?

Also, how can I visualise the LEM and LTSA output object?
When I try

Y_LEM = transform(LEM,data_array; k=12, d=2, t=1.0)
Plots.scatter(Y_LEM, title="ManifoldLearning: Laplacian Eigenmaps")

it get the error message

No user recipe defined for LEM.ManifoldLearning

Help much appreciated!
