Scaling precision for complex medical pathways
Client
AMBOSS provides a leading medical knowledge platform serving more than a million healthcare professionals worldwide.
A critical part of this platform is an interactive diagramming tool that allows medical professionals to create complex medical and chemical graphs that must be both visually clear and technically accurate.
Baseline
The AMBOSS internal tool, built on @xyflow/react, was already a capable system featuring a custom design system, interactive flowchart editing, advanced edge labeling, and used a state management architecture powered by Zustand.
Performance bottleneck
Team encountered a technical hurdle regarding node connections, as medical flowcharts grew in complexity.
Complex multi-segmented paths required significant computational overhead, leading to costly recalculations during node movement.
Precision and control
Medical professionals needed the granular control to manually adjust intricate diagrams for maximum clarity.
To provide the manual precision and stability required for professional medical documentation, AMBOSS sought to transition to stable, reshapable orthogonal edge system.
Specialized solution integration
Rather than continuing to iterate on a purely algorithmic approach, AMBOSS turned to Synergy Codes for a ready-made solution from their Overflow component library. The implementation focused on providing proven reshaping functionality for orthogonal edges, offering stability and reliability the medical platformrequired.
Because AMBOSS had clearly defined their technical requirements, the integration was remarkably smooth. The delivered solution:
- Preserved innovation:Â Synergy Codes integrated the new system with AMBOSS's existing automatic pathfinding functionality to route connections intelligently around nodes.Â
- Enhanced existing features:Â The custom draggable edge labels developed by AMBOSS worked perfectly with the new reshaping system.Â
- Delivered immediate value:Â The stable reshaping worked right out of the box, requiring minimal customization to meet professional standards.Â

The impact of this technical evolution was immediate and transformative
Medical professionals can now create and edit diagrams without the interruption of unpredictable line behavior.
Users kept all their familiar features while gaining rock-solid stability in edge manipulation.
Diagrams maintain clean, professional layouts that are crucial for precise medical communication.
The AMBOSS development team can now focus on new educational features instead of maintaining complex edge-routing algorithms.
Looking forward
This collaboration demonstrates the power of utilizing specialized component libraries to solve complex technical challenges.
By leveraging the battle-tested Overflow reshaping component, AMBOSS transformed a technical bottleneck into a seamless, high-performance experience for medical professionals worldwide.
The Overflow component library solved our edge editing challenges by providing a robust foundation for manual manipulation. The solution was stable enough to integrate seamlessly with our existing custom features, proving that specialized libraries can effectively accelerate the development of complex tools like medical flowchart editors.
