========================== K-Means Algorithm Showcase ========================== K-means is an unsupervised clustering algorithm which does not require any pre-labelled data to build a model. The algorithm groups data into k clusters, each represented by its cluster centroid. The user needs to provide the value of k (the number of clusters). Our first example will build a clustering for a random dataset (a different one each time) consisting of two variables, age and income, for each person. The task begins by randomly choosing k (3) centroids (shown as X's in the graphic). Each point is also coloured according to its nearest centroid. Close the graphic window using Ctrl-W.
