Step-by-step explanation:
The unique feature of Tableau that is being referred to in the student's question is d. In-depth insights and "what-if" analysis. Tableau is widely recognized for its powerful data visualization and analytical capabilities that allow users to create complex visual representations of their data and to conduct in-depth insights.
A key strength of Tableau is its ability to perform what-if analyses, which can help users understand the potential impact of different scenarios by manipulating data variables. This feature enables decision-makers to predict outcomes and make informed decisions based on the processed data, unlike simpler features such as encapsulation, allocation, or translating coded values. As an advanced data visualization tool, Tableau's what-if analysis is quite sophisticated when compared with other analytics platforms.
