i think you can add two visuals and add a box and set the two visuals to the front level. It looks like two visual in one box. Actually it is the combination of three visuals(one chart visual, one line visual and one rectangle shape)

Firstly why do they need to be in a single container? What are you trying to achieve?

You could group two visuals

If they have to be in the same container you need to use a custom visual like DENEB
