Median RTT per country and US state

Mapping RTT by political boundaries can reveal where high latency issues are located.

Path Dispersion

The paths taken by different traces show where the majority of a monitor's traffic travels.

RTT Distribution

An RTT distribution shows the general latency between a monitor and the rest of the Internet.

RTTs vs. Distance

Comparing RTT with geographical distance helps show if latency is primarily due to distance or other factors.
