Requirements :-

(1) Espressiff's ESP-WROOM-32

(2) Authentication key :- https://developers.google.com/maps/documentation/javascript/get-api-key

(3) Arduino IDE installed with the latest version of https://github.com/espressif/arduino-esp32

(4) Code :-

The client.print("<body>.....etcetcetc part of the the code is where all the action takes place.

client.print("<body>........etcetcetc 

You will need to place your Authentication code into the marked region in the program i.e.

place_your_authentication_key_here

Download the code to the ESP32 and reset , it will search your WIFI port and connects presenting the serial port with an IP address which is placed into your web browser/phone to view the graphic data.

You can adjust the zoom factor and its also possible to overlay roads and even earthquake data.

For some interesting locations substitute these latitude and longitude settings
