You created a set of reports about your company sales in the US in Power BI Desktop and published it to Power BI Service. You want to add a visual control to one of your reports that would segment sales data by the State and City. 
What type of Power BI visualization should you use to accomplish your goal?

Answer options:

A.Tree-map
B.KPI
C.Multi-row Card
D.Slicer
E.Key Influencers

Correct Answer: D 
Power BI`s Visualization panel provides access to the various data presentation tools, like bar and column charts, combo (a combination of line and bar charts), line, area, and pie charts. You can also find scatter plots, cards (single number and multi-rows), KPI, Key influencers, maps, matrix, Q&A, tables, etc. You can even add a Power Apps created for Power BI to your report. 
If you need to segment data by a specific value or values, a slicer is the most powerful control to do that (Number 1). You can select a visualization control, put it on a canvas and add the data. In our case, we can add State and City data (Number 2). 

Option A is incorrect because Treemap is a chart control with colored rectangles where the rectangle`s size represents the value. This control does not segment the report data by specific value.
Option B is incorrect because KPI is a visual control that presents progress to your goal, like the current amount of the raised funds against the goal in a fundraising event. This control does not segment the report data by specific value.
Option C is incorrect because a Multi-row card is a visual control that presents a piece of information in several rows as a card. This control does not segment the report data by specific value.
Option E is incorrect because Key Influencers is a visual control that helps you analyze the variations between data sets. The control automatically creates the appropriate charts to illustrate the data variations and provides users tools for interactive data analysis. This control does not segment the report data by specific value.
