The purpose of the below code snippet is to select samples from the iris data set for modeling, create a seaborn cluster plot, build a model of the features in the iris dataset, and separate the iris data set into features and a target. The code snippet imports pandas, numpy, pyplot from matplotlib, and seaborn libraries, loads the iris dataset, drops the 'species' column to create the X_iris dataset, and assigns the 'species' column to the y_iris dataset.
