I don't think there's one idiomatic way to do this.
- For HTML and Info we have commands that create (and display) a separate
  buffer containing the rendering.
- For doc-view-mode and hexl-mode we have commands we swap between the
  two views within the same buffer (usually using C-c C-c to go back to
  the "source", but it could probably be used more generally as "swap").
- In nhexl-mode, the user-view is similar to hexl-mode, but the buffer
  is not modified (the rendering is done via overlays and `display`
  text properties).
The first option is usually easier.
