Geograpfic map of premisses

Hey,
I have several esp32 in my garden, which use mqtt to publish to a raspberry pi. All done using node red.
I want to use a map of my garden, where i can visualize my sensors. Basically a google maps map, where the sensors are represented by a pin. If u then click on a pin (sensor) you get additional informations about that sensor. Are there any ideas how to do this?

Thanks
