D2 Diagram Examples

This page demonstrates using the VitePress D2 diagram plugin to create and configure both simple and complex diagrams.

Some of the below examples are copied from the official documentation, which you checkout to see the full capabilities of D2 diagrams.

Simple Diagram

```
x -> y: hello world
```

Custom Diagram Config

```d2
:::config
layout: DAGRE
theme: GRAPE_SODA
darkTheme: BUTTERED_TOAST
:::

x -> y: hello world
```

Animated Diagram

```d2
direction: right
x -> y: hi {
  style.animated: true
}
```

Sketch Style Diagram

```d2
:::config
sketch: true
:::

Write Replica Canada <-> Write Replica Australia

Read Replica <- Master

x -- y

super long shape id here -> super long shape id even longer here
```

Sequence Diagram

```d2
shape: sequence_diagram
son -> father: Can I borrow your car?
friend -> father: Never lend your car to anyone to whom you have given birth.
father -> father: internal debate ensues

```

Composition Diagram

```d2
:::config
animateInterval: 1200
fileType: GIF
:::
