title: Datasets for clustering algorithms
body: <p>I am asked to give a lecture on clustering algorithms for an audience that is not very technical. With that in mind, I wanted to do a simple exercise where I will ask the audience to identify groups from a dataset. However, I cannot find good datasets that could be usable for this purpose.</p>
  
  <p>Is there a dataset of customers and some products they have bought that I can use for this purpose? Or any other dataset that might look suitable!</p>
