How to plot your graph. A distance/time graph shows time on one axis (x) and distance on the other axis (y). It is important to plot the important information from the problem.

Particular stars called Cepheid variables allow astronomers to determine distance, and Hubble spotted one of these within M31 ...

Refining with colors. Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.
