How to create a boundary in PCA/t-SNE plot?

I am wondering if there is any possible way to plot a graph, like the one in link below, within KNIME? Any help/suggestions would be appreciated.

Figure - PMC (

I’m pretty sure the authors drew that shadowed area in by hand.

Hi @mpepper -

I’m afraid there’s not a node dedicated to this kind of boundary plotting in KNIME. That said, you could probably tackle it with a bit of Python or R code inside a related Snippet node.
