Connection Markers

Description

This example now shows the three main ways to work with connection markers.

  • Use built-in shape markers when you want a quick default setup: <f-connection-marker-circle /> and <f-connection-marker-arrow />.
  • Use custom svg[fMarker] when you need product-specific geometry, sizing, or branding.
  • Use EFMarkerType.START_ALL_STATES and EFMarkerType.END_ALL_STATES when the same marker should be rendered for both normal and selected connections.

Markers are useful when the meaning of an edge matters: direction, approval, success or failure paths, or domain-specific relationship types. They let you add meaning to a connection without changing routing or building a custom connection renderer.

In this demo:

  • The first connection uses the built-in circle and arrow markers.
  • The second connection uses custom SVG markers that apply to both normal and selected states.
  • The third connection shows the fully explicit mode, where normal and selected markers are defined separately.
