Violet can draw UML activity diagrams, but the tool cannot decide what the process should mean.
Before opening the diagram editor, write the process in plain language.
For example:
Once the flow is clear in words, Violet can help you express that same meaning with UML notation.
Open Violet and create the activity-diagram type used by your course.
The workspace provides the elements needed to represent activity flow.
At this stage, focus on the elements you have already learned:
Use only the notation required for the current model.
Begin with one clear start node.
Place it where the flow can be followed naturally through the page.
A readable layout often moves primarily from top to bottom or left to right.
The exact direction matters less than consistency.
The reader should not have to guess which connector to follow first.
Add the actions that occur before the decision.
For the soccer example:
Read player availability
Action names should describe what happens.
Avoid labels such as:
Those labels make the diagram dependent on another explanation.
The diagram should communicate meaningful behavior on its own.
Place a decision node after the action that provides the information needed for the choice.
The decision should represent a specific question:
Is the player available?
Create outgoing flows for the possible results.
Label those flows so the reader can tell when each path applies.
For example:
[available][not available]The path labels should match the condition being modeled.
On the available path, add:
Add player to available list
On the other path, the process may simply continue without that action if that matches the requirements.
Do not add fake “do nothing” boxes simply to make both branches look symmetrical.
Model meaningful behavior.
If both paths later perform the same work, arrange the connectors so the reader can see where the paths rejoin.
For example, both paths might continue to:
Display roster
The visual layout should make it clear which actions belong only to one path and which actions happen afterward for both paths.
Finish the modeled activity with an end node.
The end should be reachable from the flow you intend to model.
If an arrow stops in empty space or a path has no clear continuation, the reader cannot tell whether the process is incomplete or intentionally finished.
Once the diagram is drawn, read it from the start node.
For each element, say in plain language:
The diagram should tell the same story as the process you planned before opening Violet.
If the story changes when you read the diagram, revise the UML.
Do not add extra decisions, data details, object fields, or unrelated process steps simply because Violet has tools available for them.
A strong activity diagram is not the one that uses the most shapes.
It is the one that communicates the intended flow accurately and clearly.
Save the current Violet file using the filename and location required by the course.
You may need to revise it after using the Feedback System.
The editable diagram is the source artifact.
A screenshot can show the diagram but does not replace the file you need for later revision.
A useful workflow is:
Describe the process → Draw the flow → Read the diagram → Compare it with the requirement → Revise
Violet records the model.
Your reasoning determines whether the model actually represents the process.
