Node-Red organisieren mit link-in bzw. link-out am Beispiel: Covid-19 Dashboard

Wie können die Flows in NodeRED organisiert werden? Damit ein Flow nicht überladen wird und auch um die GUI von der Logik zu trennen (MVC, Model View Controller Konzept) können die link-in bzw. link-out Nodes verwendet werden. Das sind diese:

Die link-out Nodes werden in den Quell Flow integriert, z.B.

Und in den neuen Ziel Flow die link-in:

Schon haben wir ein Dashboard:

Hier der Code des Covid-19 Dashboards:
