This chapter introduces advanced techniques for exploring data, focusing on data visualization, the creation of subsets, and the analysis of specific columns within datasets. Readers will learn to generate and interpret histograms, box plots, and scatter plots to gain deeper insights into the structure and distribution of data. This chapter also explores strategies for handling formatted data, creating new variables, and extracting meaningful subsets of data based on specific conditions. Practical examples using the Museum of Modern Art (MoMA) dataset illustrate these concepts.
