What visualization technique best representing communication methods between devices in your network?

• A. Network graph
• B. Bar chart
• C. Pie chart
• D. Table

Answer: (A)

Representing how devices communicate in a network is best shown with a network graph because it maps relationships directly. In a network graph, each device is a node and each communication channel is an edge. You can encode additional information with edge weights for traffic volume and use direction to show who initiates communication, giving a quick view of topology, central devices, clusters, and potential bottlenecks. This visualization makes it easy to spot patterns like dense subnets or critical links whose failure would impact many devices. A bar chart only compares quantities across categories and doesn’t reveal connections between devices. A pie chart highlights proportions of a whole, not network structure, and a table lists data without visualizing relationships, making interconnections harder to grasp at a glance.
