How to center a mermaid graph in pdf Quarto?

```{mermaid}
%%| fig-align: center
flowchart LR
  A[Hard edge] --> B(Round edge)
  B --> C{Decision}

As you can see the graph is not centered in the document. So I was wondering if anyone knows how to center a mermaid graph in pdf Quarto? I'm using Quarto v1.4.

Solution

  • Once the %%| label: argument is set to fig-SOMETHING then the fig-align argument works properly.

```{mermaid}
%%| label: fig-figure
%%| fig-align: center
flowchart LR
  A[Hard edge] --> B(Round edge)
  B --> C{Decision}
```

    Output:

    My guess is that quarto needs to know that the chunk is producing a figure for other figure arguments to take effect. By including %%| label: fig-figure quarto then will process fig-align arguments.
