A canned food manufacturer has its manufacturing plants in three locations across a state. Their product has to be transported to 3 central distribution centers, which in turn disperse the goods to 72 stores across the state. Which of the following visualization tools could help understand this problem better? a. A scatter chart
b. A time-series plot
c. A network graph
d. A contour plot

Network graph

Step-by-step explanation:

Given

Central Locations = 3

Stores = 72

From the question, we understand that the goods has to be transported from 3 locations to 72 others.

Of all 4 options, the best tool to visualize this scenario is the network graph.

With the network graph, the manufacturer can see the structure and links between each central location and the other 72 stores because each related point on the graph are interconnected across one another.
