The term "drill down" in Tableau refers to the ability to view a more detailed level of data within a hierarchical structure. When you drill down, you navigate from summarized or aggregated data to more detailed, granular data points. This is particularly useful in situations where you want to analyze specific aspects of your data, such as going from yearly sales figures to quarterly, monthly, or even daily sales data.

Hierarchies in Tableau, such as dates (Year > Quarter > Month > Day) or geographic locations (Country > State > City), allow users to explore data at different levels of detail. By drilling down, you are effectively uncoupling the aggregated view to reveal underlying patterns, trends, or insights that might not be visible at the higher levels of summarization.

In this context, removing a dimension from the view, aggregating multiple data points into one, or changing the data source does not relate to the specific act of drilling down into a hierarchy for more detailed information. Each of those actions serves a different purpose in data analysis and visualization.
