Add a widget preview when adding widgets to dashboard

Is your feature request related to a problem? Please describe. I have nightmares about accidentally adding the wrong widget to my dashboard.

Describe the solution you'd like Give me a preview of each widget that I can select to add to my dashboard.

Describe alternatives you've considered A possible alternative could be allowing visualization selection from within the widget addition modal. This would let the user control exactly what visualization they're adding to their dashboard.
