Plotting basic arrays

Arrays are one of the fundamental data structures used in data analysis to store various types of data. They are also a quick way to store columns or dimensions in data, for statistical analysis as well as exploratory analysis through plots and visualization. Arrays are also very easy to plot, as they are simple. When a visualization is being done with two columns of a dataset, it means that the two column values are taken in the form of separate arrays and then plotted against each other, which again makes arrays very important.
