reveal.js : how to set specific figure size with R ?

[wilcar]

I am using mermaid within DiagrammeR package to create an ER diagram but my output is very small. How can I set the output size in revealj presentation ?

## slide

<script src="https://cdn.jsdelivr.net/npm/mermaid/dist/mermaid.min.js"></script>

<script>mermaid.initialize({startOnLoad:true});</script>

library(DiagrammeR)
mermaid("
erDiagram
FROM ||--|{ TO : Flow
")
