How to supply event coordinates for real-time insights events?
<p>When we look at the IoT Real-Time Insights service, we see that it provides a visual mapping capability.  Unfortunately, the current documentation on using this appears to be very light.  What should the JSON string structure of an incoming event contain to provide latitude and longitude data to the Map widget within a Real-Time Insights dashboard?</p>
