Clustering case chart

[dlubbers3 (David Lubbers)]

In Mathematica I saw an awesome chart for clustering cases, e.g. a disk inside an anulus. I want to put that chart, suitably credited, into a word document. Anybody know where that figure is? It is not revealing itself to me. ):

Thanks

We have it in several places in the documentation. You can cite it from here for example:
