====================================================
Calculate Diffusion Components (`scanpy.tl.diffmap`)
====================================================

Calculate diffusion components from single cell KNN graphs.

This requires to run `Scanpy ComputeGraph`, first.

It yields `X_diffmap`, the dimension-reduced representation in diffusion
components space.
