Connections always start from the Starting Node. Drag nodes from the palette onto the canvas. To connect: click a port (circle at the bottom or side of a node), then click the node you want to connect to. You can also drag from the port to the target node. Port colours indicate outcomes (e.g. green = success/delivered/true, red = failed/false, blue = continue). One node can have multiple outgoing connections (e.g. condition → true path and false path). To remove a connection, click the connection line between the two nodes.
