1. Overview
This section consists of the 3 tabs: Overview, Warnings, and Reproduction.
2. Variables
This section of the report gives a detailed analysis of all the variables/columns/features of the dataset. The information presented varies depending upon the data type of variable.

4. Missing values
The report generated also contains the visualizations for the missing values present in the dataset. You get 3 types of plot: Count, matrix, and dendrogram.
