Nodes

Nodes are the building blocks of your flowchart. Declare a node by writing its name, optionally followed by shape and style properties.

Start Process
Check Input
Process Data
End

Node Shapes

DrawGPT supports multiple node shapes to represent different types of steps. Use the [shape: name] syntax:

Shape	Syntax	Typical Use
Rectangle	`[shape: rectangle]`	Process / action steps
Rounded Rectangle	`[shape: rounded-rectangle]`	Start / end terminators
Diamond	`[shape: diamond]`	Decision points
Cylinder	`[shape: cylinder]`	Databases / data stores
Circle	`[shape: circle]`	Connectors / users

Start [shape: rounded-rectangle]
Validate Input [shape: diamond]
Process Order [shape: rectangle]
Save to DB [shape: cylinder]
End [shape: rounded-rectangle]

Shapes matter

Using the correct shape makes your flowchart instantly readable. Diamonds always mean "decision", cylinders always mean "data store" — following standard flowchart conventions.

Edges (Connections)

Connect nodes with directional arrows using --> syntax. Add labels in brackets to annotate the edge:

Start --> Validate Input
Validate Input --> Process Order: [Valid]
Validate Input --> Show Error: [Invalid]
Process Order --> Save to DB
Save to DB --> End

Edge Labels

Labels appear on the connecting arrows. They're especially useful for decision branches:

Check Payment [shape: diamond]
Fulfill Order [shape: rectangle]
Send Error [shape: rectangle]

Check Payment --> Fulfill Order: [Payment Success]
Check Payment --> Send Error: [Payment Failed]

Styling Nodes

Add icons and colors to nodes using bracket syntax:

User Input [shape: rounded-rectangle, icon: user, color: #3B82F6]
API Call [shape: rectangle, icon: server, color: #10B981]
Database [shape: cylinder, icon: database, color: #8B5CF6]

Examples

A straightforward linear process:

Receive Request [shape: rounded-rectangle, color: #10B981]
Parse Input [shape: rectangle]
Validate Data [shape: rectangle]
Save Record [shape: cylinder, color: #3B82F6]
Return Response [shape: rounded-rectangle, color: #10B981]

Receive Request --> Parse Input
Parse Input --> Validate Data
Validate Data --> Save Record
Save Record --> Return Response

A flow with conditional branching:

Start [shape: rounded-rectangle, color: #10B981]
Check User Role [shape: diamond, color: #F59E0B]
Admin Dashboard [shape: rectangle, color: #3B82F6]
User Dashboard [shape: rectangle, color: #8B5CF6]
Guest Page [shape: rectangle, color: #6B7280]

Start --> Check User Role
Check User Role --> Admin Dashboard: [Admin]
Check User Role --> User Dashboard: [Registered]
Check User Role --> Guest Page: [Anonymous]

A flow with retry logic:

Start [shape: rounded-rectangle, color: #10B981]
Send Request [shape: rectangle]
Check Response [shape: diamond, color: #F59E0B]
Process Data [shape: rectangle, color: #3B82F6]
Log Error [shape: rectangle, color: #EF4444]
Retry [shape: diamond, color: #F97316]
Fail [shape: rounded-rectangle, color: #EF4444]
Done [shape: rounded-rectangle, color: #10B981]

Start --> Send Request
Send Request --> Check Response
Check Response --> Process Data: [200 OK]
Check Response --> Log Error: [Error]
Log Error --> Retry
Retry --> Send Request: [Attempts < 3]
Retry --> Fail: [Max Retries]
Process Data --> Done
