The problem is that a node contains an embedded playground that produces text as output when executed (for example the playground reads a file or scraps HTML or calculates a hash), the text of the playground is replaced with the executed output. If the playground produces a visualization or non-textual output, this doesn't happen.

There is any way to do this?
