This image shows the trace details of a selected trace. 
The top pane shows summary information including the status, number of span errors and whether the trace was abridged or not.  The number of services, number of total spans, depth of spans, start time and duration and trace ID complete the information shown.
The second pane in the image is the topology view of the trace.  The circular nodes represent the calling and called components in the trace, colored to indicate the service that they are part of.  The arrows between nodes indicates the relative performance of each call with thicker arrows indicating longer times.
The table at the bottom of the image show the same information from the topology view but in a hierarchical list of spans including their component type and duration offset within the trace duration.  Each span is a link to span details and each row contains a 3-dot menu at the right edge, providing several navigation options including customizable drilldowns to DB Management, Logging Analytics, and other locations.
