Attaching a Status Box to an Object/Point

1. A concise explanation of the problem you're experiencing.

I have several sets of sensors that I want display diagnostic data from. I'd like a little floating text box/bubble that would hover next to each of the sensors (displayed as points on the map). Ideally, the diagnostic data would draw from a REST API/other data steam.

Is this something that can be done?

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

I don't know how to do this

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

I'd like this so that I/my users can easily see what the sensor statuses are.

4. The Cesium version you're using, your operating system and browser.
Cesium v1.5.1, Windows 10, Chrome 70

I think the easiest way to do this would be creating a label:

Which I believe is just HTML/CSS so it can be styled easily. Here’s the full doc for it:

Let me know if that solves your issue!
