+# Create Data Flow Diagram - Validation Checklist
+
+## DFD Notation
+
+- [ ] Processes shown as circles/ellipses
+- [ ] Data stores shown as parallel lines or rectangles
+- [ ] External entities shown as rectangles
+- [ ] Data flows shown as labeled arrows
+- [ ] Follows standard DFD notation
+
+## Structure
+
+- [ ] All processes numbered correctly
+- [ ] All data flows labeled with data names
+- [ ] All data stores named appropriately
+- [ ] External entities clearly identified
+
+## Completeness
+
+- [ ] All inputs and outputs accounted for
+- [ ] No orphaned processes (unconnected)
+- [ ] Data conservation maintained
+- [ ] Level appropriate (context/level 0/level 1)
+
+## Layout
+
+- [ ] Logical flow direction (left to right, top to bottom)
+- [ ] No crossing data flows where avoidable
+- [ ] Balanced layout
+- [ ] Grid alignment maintained
+
+## Technical Quality
+
+- [ ] All elements properly grouped
+- [ ] Arrows have proper bindings
+- [ ] Text readable and properly sized
+- [ ] No elements with `isDeleted: true`
+- [ ] JSON is valid
+- [ ] File saved to correct location
