Study IQualitatively Understanding The CS

Study IIAxis Direction And Sequence

Animation or varying size over time might be able to mitigate this confusion.

Guidelines• Give salient cues for the flow of time.

• Give explicit reminders of two oriented axes.(Do better with annotations)

• DALC is better for presenting correlation(Need more understanding)

• Questions about complexity: Having a small number of unique shapes and features will likely make for a more memorable and understandable graph

• Good for tracing and interacting with timeline (better with animation)
