Hi Lan Price,
There is a problem with the markers and we will fix it with the next internal build scheduled for the middle of the next week.
The problem is the position property of the markers. And we will make it to work andwe will rename it to location. So the new property that you need to set is http://docs.kendoui.com/api/dataviz/map#configuration-markers.location
Can you please update to the next internal build and if you find something that is not working please contact us for a quick fix.
Thank you for the help. I have updated your point.
