Viz to load an Image and put dots with XY positioned showing measures

I miss a visualization that I can create a page to see diferents measures working together. Especialy for Iot aplications, I would like to put a dot (or other shape) corresponding a sensor of one asset in a chart with an image in background. For example an see readings of a motor in realtime.

In a sencond aplication, I would like to put an image of some area of my plant an put some dots that represents an overall situation of a measure in realtime. It would be useful to see with color scale if my operation is good or not and which point is out of limits.
