Basic Conditional "Indicator" Visual

Hi All,

I'm in the process of creating a suite of reports for my company, within this is a sub-catagory of "Policing" reports to make sure data from various sources is as it should be. These are split into their own catagories on a policing homepage (the whole report is navigatable with buttons and bookmarks for an app-like experience). I've already got a handy tooltip visual from the marketplace that lets the buttons show a breakdown of the number of objects to be actionned within that section. However, what would be really useful would be a very simple visual which doesn't have to show any data, it simply needs to show a shape (small circle or square) which changes colour based on the number of objects requiring action in the page.

Hopefully something like this exists or can be achieved in one way or another from another visual type! Let me know if anything needs clarifying however,

Thanks in advance :)
