How do I visualize the magnetic field?

[Sketchy]

TL;DR

Need to visualize how the magnetic field around a transformer drops in intensity (mikro tesla) depending on the distance from it using real measured values.

Hi!

So my question is this, I have done measurements with an magnetic field meter around a transformer from 0.5 meter away (then measure some points around) and then I moved out 0.5 meters and so on until I reached a nearby building.

So my issue now is I want to visualize this to my customer in an easy way, I'm thinking like a 2D "aerial" view with the transformer in the middle and red/green gradient moving out depending on the value from my measuring device at that point. Is there any software that does this or do you have any other suggestions on how I can show this?
(The purpose is to show that the magnetic field at the nearby building is not an any harmful levels)

Are you familiar with the different options for making 3D plots in Excel? You can do a search to see the different styles that are available...

Also, I'm assuming that these are 50/60Hz AC Mains fields, right? Did you record the orientation of the maximum field at each measurement point as well?
