       | Guess that would help if I already knew what a dataframe is!

         | You can query/filter/sort and pick /transform data on multiple

         | 
         | It's used for data mining, ML etc.
         | 
         | It's basically like working with a spreadsheet/sql table

         | 
         | Every row is a distinct entity. Every column is usually stored
         | / treated as its own distinct array.
