Services interaction diagram Graphviz Example

A Graphviz example of a microservices interaction diagram where edge color and label encode latency between services.

Every call between services is a directed edge whose label shows the latency (e.g. 552ms) and whose color/fontcolor encodes health — green for fast, orange for borderline, red for slow. This turns a plain call graph into a lightweight latency heat-map you can read at a glance.
