Curved Connectors
This feature allows a user to display relations of an element by clicking on it. In Getaviz, connectors between elements were traditionally drawn as straight lines. With this feature, they can also be drawn as curved instead. This is meant to increase the clarity of the visualization.
A new file ui/scripts/Relation/RelationCurvedConnectionHelper.js defines a function object named createCurvedRelationConnectionHelper. This function object takes a controllerConfig as input and contains all necessary logic for drawing curved connectors. Based on configuration, either straight or curved connectors will be created in the activate() function in ui/scripts/Relation/RelationController.js.
To react to user clicks, a new selected event has been introduced. A new controller CanvasSelectController.js publishes this new event based on user input.
The Curved Connectors feature can be enabled or disabled as part of the controllerConfig in a setup. It is enabled by default in the example setup ui/setups/relations.js.
This feature can be tested using the relations setup under ui/setups/relations.js and the example model under ui/model/example.
