The distortion is such that the landmarks of the source are mapped to those of the target. Flip the tree to get it horizontal, and use coloring to highlight clusters. If you decide to select as target the current source, your new selection will be honored, but the source image will be changed as well to reflect another arbitrary choice (it is not possible to register an image to itself). Sven has shown how to use the class gaussian_kde from Scipy, but you will notice that it doesn't look quite like what you generated with R. This is because gaussian_kde tries to infer the bandwidth automatically. It adds insight to the chart. Furthermore, it often makes sense to increase the upper y-axis limit, since the density plot may be cut off otherwise.
