I'm working on an application where the user is shown a map with some data on it. In mapping, there are different ways to classify the data, so the client would like to give the user the ability to change the classification scheme to show a different story in the data and they'd like it to be incorporated into their already created settings panel.
The current settings panel looks something like this:

I have lots of space to work with as the task doesn't require much room at all. I would like to include some sort of description on how each classification scheme works as the users might not know.
I was thinking of doing something like this to fill the empty space, but I'm not sure if this is the correct way to move forward:
Question
Should I try to fill the empty space with something or will it be fine to have just radio buttons and blank space?
