Explanation
If a stakeholder wishes to build a Freeform Table in Analysis Workspace that consists of a list of specific pages on the company website and the number of visits to them, but they are not able to find a page dimension item for an existing page that they are looking for, the best option is to scroll down to the bottom of the page dimension list inthe left rail and select "Show Top Items From Last 6 Months". This will refresh the page dimension list and show more items based on the last six months of data. Changing the workspace date range or using a custom date range in a Freeform Table will not affect the page dimension list in the left rail.

Explanation
A Map Visualization can be built by representing geo segmentation data about visitor location on the DMA or Zip Code level, which are two dimensions that can be used in a map. Alternatively, a Map Visualization can be built by using one metric (including calculated metrics) that can be applied to any dimension that has geographic data associated with it, such as country or region.
