 ### Shapefile
 
 Shapefiles are a widely-used format for storing geographic data. They typically come as a set of files with different extensions working together. For example, a complete shapefile often includes files with extensions like:

 Projections are coordinate systems used to represent the 3D curved surface of the Earth on a 2D flat surface, like a computer screen.
 
-Different projections change how shapes, distances and areas appear. Some projections preserve shapes, while others maintain accurate sizes.
+Different projections change how shapes, distances and areas appear. Some projections preserve shapes, while others maintain accurate sizes, but all projections stretch and change the geography in some way to flatten it out.
 
 For Datawrapper, we need our geographic data projected using the **WGS84** system, which is a commonly used standard for mapping and global positioning.
