Type Property

"type": String

The type of map viewer to use. There are two options:

DeviceAutoBreakpoint Property

"deviceAutoBreakpoint": Number

When the "device" property is "auto", this value is used to detect if the device is "desktop" or "mobile". The width of the browser frame is compared with this property, and if the browser frame width is the larger value, then the "device" property is "desktop"; otherwise "mobile" is used.
