Visualize multiple latitudes and longitudes together

[bhaskar-anand-iith]

Is it possible to visualize an array of lat lon on mapviz?
Basically, I have multiple lat lon data of vehicles in the scene. The lat lon represents the vehicle location. For every frame I get lat lon data array which is of varying size. Say, the first frame has 4 cars, second has 3 and third has 1. So I need to visualize 3, 2 and 1 dots (lat, lon) respectively in three consecutive frames.
If anybody can help or suggest any way it can be done...

The most flexible message types to visualize are the Marker or MarkerArray. You can provide a set of points to visualize with those.
