Allow visualization of outputs

[bytebutcher]

Just an idea to play around with:

Allow the visualization of data. This could be a tabbed view (like the log and hex view).
It might visualize data based on a VisualPlugin?
It would be nice to display mermaid diagrams / plantuml. Or to show diagrams which visualize the character distribution.

We might also just add a new "Visualize: [Visualizers...]" combo box.
