Which command displays network bandwidth usage in a continuous graph format?

The command that displays network bandwidth usage in a continuous graph format is iftop. This utility monitors network traffic, providing a real-time view of bandwidth used by different hosts on a network interface. It presents the data in a tabular format, allowing users to visually analyze the flow of traffic over time, making it a powerful tool for tracking network performance.

MTR is primarily a network diagnostic tool that combines the functionality of ping and traceroute to provide information about the path data takes to a destination, along with round-trip times. Although it can provide some insight into network performance, it does not display continuous bandwidth usage in graph format.

Traceroute is designed to show the path that packets take from one network node to another, detailing the number of hops and response times, but it doesn't offer a continuous bandwidth usage display.

Ping is primarily used to test the reachability of a host on a network and to measure round-trip time for messages sent from the originating host to a destination computer. While it provides valuable information about network connectivity, it does not show bandwidth usage continuously.

Therefore, iftop is the correct choice as it specifically focuses on displaying bandwidth usage in a continuous graph format, making it an essential tool for network administrators and users wanting to monitor network performance
