-----------------------------------
Summary: camel-diagram - Add topology diagram renderer for
inter-route visualization
Key: CAMEL-23661
URL: https://issues.apache.org/jira/browse/CAMEL-23661
Project: Camel
Issue Type: Improvement
Components: camel-jbang
Reporter: Claus Ibsen
Add a topology diagram renderer to camel-diagram that visualizes inter-route
connections (the route graph). This complements the existing route-structure
diagram which shows intra-route EIP trees.
The topology renderer should:
- Use the RouteTopologyDumper SPI (CAMEL-23656) as data source
- Support PNG and ASCII/Unicode output (same as route diagrams)
- Reuse existing color themes, rendering primitives, and dev console patterns
- Use a layered graph layout algorithm (Sugiyama-style) for node placement
- Classify nodes visually: triggers (timer/quartz/cron/scheduler) vs regular
routes
- Classify edges: internal (direct/seda) vs external (kafka/jms)
- Support runtime metrics (per-route exchange counters) on nodes
- Support highlight mode for tracing message flow across routes
- Integrate with camel-jbang CLI (camel cmd route-topology --diagram)
This builds on CAMEL-23656 which provides the topology data model.
