Coral

Appearance

Get started with Coral ​

Build, connect, reflow, save, and export a two-object diagram in about five minutes.

Before you start ​

  • Use a supported desktop browser.
  • Allow the application to finish loading before editing.

1. Start a blank diagram ​

Select Blank diagram with Create Node from Welcome to Coral. The application opens one empty local document and the create-node dialog.

2. Add the first object ​

Choose a symbol, enter API service, and select Create node.

DSL:

coral
service "API service" as api

The API service appears on the canvas and in the DSL editor.

3. Add and connect another object ​

Open Command palette > Create Node, create Database, then open Command palette > Create Edge and connect the two objects.

DSL:

coral
service "API service" as api
database "Database" as database
api -> database [label: "writes"]

The canvas shows two objects joined by a labelled connection.

4. Reflow and save ​

Open Command palette > Reflow Layout, then select Save. The objects use the current layout and a versioned .coral.json document is saved.

5. Export the result ​

Open More actions > Export SVG. The browser saves a graphic export of the current verified diagram.

What you built ​

A local two-object diagram with source text, layout, document state, and an SVG export.
