Key Facts
- A diagram should answer one defined question.
- Every arrow needs a stated meaning.
- Reveal information in the order it becomes useful.
- Separate a simplified model from a claim about real behaviour.
What Is The Diagram's One Question?
Choose a question involving a relationship: where an item goes, what blocks a movement or how one decision changes a route. “How the whole system works” often invites more detail than a Short can explain.
This author-created example uses an imaginary parcel sorter: blue parcels go to shelf A and orange parcels go to shelf B. The sorting rule demonstrates a branching decision. It is invented for this exercise and does not describe a real warehouse.
The question is: “What happens to a parcel after its label is checked?” Draw an incoming parcel, a decision point and two destinations. Motors, scanners and warehouse architecture would add detail without explaining the route.

What Does A Reveal Plan Look Like?
Copy this author-created plan with your checked explanation beside it. For each reveal, name the parts the viewer sees, define the symbols and note what the simplified model leaves out.
Scroll this table sideways to see every column.
| Reveal | Visible Elements | Narration Job | Motion Or Label | Model Limit |
|---|---|---|---|---|
| Start | One parcel and one checkpoint | Establish the item being sorted | Label: Check colour | Fictional sorting rule |
| Decision | Checkpoint with two outgoing paths | Explain that there are two outcomes | Arrows mean possible routes | No processing delay shown |
| Blue route | Blue parcel follows path to A | Demonstrate one outcome | Shelf A remains labelled | Colour stands in for a real attribute |
| Orange route | Orange parcel follows path to B | Demonstrate the other outcome | Shelf B remains labelled | Only two categories represented |
| Complete view | Both paths and destinations | Restate the rule visually | Movement stops for inspection | Exceptions excluded |
Write the arrow meaning beside the plan. In this example, an arrow means a possible direction of travel. It does not represent speed, pressure, probability or the amount of material.
The completed view lets the viewer inspect the whole relationship after learning its parts.
Give the blue parcel an A tag and the orange parcel a B tag, matching the destination labels. The written tags let viewers follow the route without relying on the colour distinction alone.
Which Details Can You Remove?
Remove decoration before shrinking labels. If a shelf texture, shadow or simulated control panel obscures the route, simplify it.
Keep labels close to their objects without covering the arrowheads. Use stable names throughout: changing from “Shelf A” to “Blue zone” midway creates an unnecessary translation task. If both names are useful, introduce their relationship once.
Avoid encoding two meanings in the same visual property. A thicker arrow should not sometimes mean “more parcels” and sometimes mean “the path currently being discussed.” Choose one meaning or use a different treatment.
For an explanation that depends on real quantities, record the source and units in the script brief. A decorative arrow must not quietly become an apparent measurement.
How Should Captions And Narration Share The Work?
Let narration explain the relationship while short labels identify parts. Copying a full spoken sentence onto the diagram can leave the viewer reading instead of inspecting the movement.
Pause the introduction of new elements during a dense caption. In the parcel example, establish “Check colour” before showing both destinations. Once the destinations are familiar, the narration can describe the two outcomes without continually relabelling them.

How Do You State The Model's Limits?
State the simplification that affects the lesson. For this example, the label “Imaginary sorter. Two categories shown” identifies both the invented mechanism and the limited set of outcomes.
For a real mechanism, identify omissions that could change the viewer's understanding. If the model skips a safety interlock, a delay or an exception, decide whether that omission is acceptable for the promised explanation. If it changes the answer, include it or narrow the topic.
Review the final diagram without sound. Then ask a viewer what each arrow means and where each parcel goes. A wrong answer tells you which relationship needs a clearer reveal, label or explanation.
Frequently Asked Questions
Should I Show The Whole Diagram Immediately?
Show enough to establish the system, then reveal detail in the order the explanation needs it. A complete diagram is useful at the end when viewers can recognise its parts.
Can Colour Carry The Entire Explanation?
Use labels, shapes or position as well. A viewer should be able to follow the main relationship without depending on one colour distinction.
How Many Labels Are Too Many?
Remove labels the viewer does not need for the promised explanation. Test the remaining diagram at phone size with the real captions.
Does A Polished Diagram Prove The Mechanism Is Correct?
No. Check the underlying explanation against suitable evidence. This guide's fictional routing example demonstrates presentation only.
