# marker

The marker icon that can be added to the component in the UI to give some extra context. The most common use case is to display e.g. a "Beta" badge to tell the user that this component is in beta. The marker must be in the Data URI image format as described here: <https://en.wikipedia.org/wiki/Data_URI_scheme>. `image/png` or `image/svg+xml` image types are recommended. The marker icon is displayed in the top right corner of the component shape.\
\
Example:

![Beta badge](/files/-M-K3NhV1AWHMnlWSaAb)

```
{
    "marker": "data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL..."
}
```
