Is it possible? Probably. but if you're new to electronics, this sounds like a very daunting task!
MySensors is very good at getting sensor data into a database wirelessly. A database/system like Domoticz, for example, will let you create graphs from your data.
Challenges to think about:
the 3D map will be very distorted.
you'll need to make software to do all this. Why not explore photogrammetry instead? There are great apps for that.
My recommendation would be to just start with making a basic sensor (perhaps something already on the Micro:bit, like the motion sensor or the magnetic sensor), and get that data into Domoticz. That will spark new ideas, ideas that you will be able to more easily make. For example, you can get some data from place A and use it to actuate a motor/turn something on in place B. One of the first things I ever did was to create a disco lamp that turns on when the temperature reaches 26 degrees celcius. When it gets summer, it's time to party!
