What does the narrator find difficult about graphing on an iPad?

• The screen is too small.

• The stylus is hard to use.

• The data is too complex.

• The graphing app is not user-friendly.

What does the narrator suggest about the initial claim after graphing?

• The claim is fully supported by the graph.
