Create Gantt Dependency Link Line

In the Gantt chart, arrows are usually used to represent the dependencies between tasks. During initialization, existing dependencies are displayed through dependency.links, and dependencies can be dynamically created through interaction. Note that you should set dependency.linkCreatable to true to enable the creation of dependency lines. The styles of the operation points and operation lines that are dynamically created during creation can be configured through dependency.linkCreatePointStyle dependency.linkCreatingPointStyle dependency.linkCreatingLineStyle.
