dataframe
Rows and columns
A dataframe is a two-dimensional data structure organized in rows and columns, like a spreadsheet or database table.
Each column typically holds a specific type of data—names, dates, amounts—while each row represents a single record or observation.
The term is most associated with the Python pandas library and R programming language, where dataframes are fundamental to data analysis: I loaded the CSV into a dataframe and filtered for sales over $1000.
