DiagrammeR::grViz() in chunk not working in new versions of Quarto

[asadow]

After updating Quarto and rendering my .qmd, I got this error output instead of the diagram: TypeError: Assignment to constant variable.

I had to downgrade back to 1.3.450 to fix it.

After updating Quarto and rendering my .qmd

Can you share you .qmd please ? This would allow to have a closer look. Or just an example of what you are doing.

Otherwise, I can only guess what you are doing. Thank you

example.qmd

```{r}
DiagrammeR::grViz("digraph {

graph [layout = dot, rankdir = LR]
node [shape = rectangle, style = filled, fillcolor = Linen]
owner [label = 'Owner', shape = circle]

}")

[cderv]

How do you render ? Which quarto version to you have ? Which version of the R package .

I can't reproduce

```{r}
DiagrammeR::grViz("digraph {

graph [layout = dot, rankdir = LR]
node [shape = rectangle, style = filled, fillcolor = Linen]
owner [label = 'Owner', shape = circle]

}")

```

I used latest pre-release Quarto 1.6.37, with R 4.4.2 and those packages versions

Huh, strange, I was using the same versions..

I suppose I'll close for now. I'm glad it works on your end.

If it does not work for you, then we need to find why. So don't hesitate to reopen and share more information.

Phenomenon explained here. So does that mean quarto is not able to preview a grviz image?

[cderv]

It seems to be a conflict with quarto preview logic and viz.js used in DiagrammeR. Let's discussin in
