# Editor Canvas

Wire Flow uses **BPMN** (Business Process Model and Notation), a standard diagram notation, to represent workflows. If you have used tools like n8n, Lucidchart, or any flowchart tool, the concepts will feel familiar.

## Elements

| Element            | Appearance                    | Purpose                                                   |
| ------------------ | ----------------------------- | --------------------------------------------------------- |
| **Start Event**    | Thinner circle                | Entry point — where the workflow begins                   |
| **Task**           | Rectangle with an icon        | A unit of work (transform, HTTP call, parse a file, etc.) |
| **Gateway**        | Diamond shape                 | A decision point — routes flow based on conditions        |
| **End Event**      | Thicker circle                | Exit point — where the workflow finishes                  |
| **Error Boundary** | Small circle on a task's edge | Catches errors from a specific task                       |
| **Sequence Flow**  | Arrow between nodes           | The path execution follows from one node to the next      |

## Connecting Nodes

1. Hover over a node — connection point options appear on its edges.
2. Click and drag from a connection point to another node.
3. Release to create an arrow (sequence flow).
