Map Widget - how does it actually work?

[Alex Tweedly]

Well, the big advantage of widgets is that you can look at the source 
code. As it says in the Livecode Lesson ( 
http://lessons.livecode.com/m/4071/l/1005132-how-do-i-modify-a-livecode-widget 
),

Unfortunately, there is a non-obvious meaning to "out of the box" - what 
it means is "source code for all the widgets provided 'out of the box' 
*in the community version* is accessible ..."

So, sadly, you can't just go look at the source code to find out what 
you need.

However, in the dictionary under "Guide" you can find some more info / 
example about the map widget. In particular, it defines the format used 
for  region, coordinates, span and markers - which is probably all that 
you need (I think all the others parameters in the API are booleans).

Disclaimer: I have never used the map widget - everything I say here is 
taken at face value from the doc and the visible files within the widget 
folder of 9.6.0(rc1)

I can’t work out anything about the format of the data you can feed in, or what it looks like when it comes out. There isn’t even enough info to start a meaningful experiment, IMHO.
