Referencing an enclosing figure hinders the diagram from being drawn.

[HerrMotz]

The *backend's* purpose is to handle the algebraic parts of the mapping between SPARQL queries and VQGs. An entity is considered to have the properties shown in #todo[insert figure here]. 

#figure(caption: [Placeholder text.],
```pintora
erDiagram
  PREFIX {
    string iri
    string abbreviation
  }

)

If I reference it using e.g. `<fig:data_types>`:

```typst
#figure(caption: [text], ```pintorita
erDiagram
  PREFIX {
    string iri
    string abbreviation
  }
```) <fig:data_types>

and call the reference using @fig:data_types, then the source is shown instead of the diagram. Do you know a fix?

Also, the figure description says e.g. Listing 5. Do you know a way how to let it be treated as an image?
