Is your feature request related to a problem? Please describe.
Instead of merely printing hard-to-understand metrics, PrivacyRaven should generate visuals and easy-to-understand metrics for this tool to be more broadly applicable. This can be solved in a multitude of ways, but user understanding should be the top priority.
