I am working on a project in processing with twitter. I am trying to visualize how topics spreads on twitter. For this I need to draw an arc or curve between two points on the map. I am using MercatorMap to display point on the map with geocoding from google api's.
I am not able to find anything which can be helpful in drawing an arc between two points on the map. Can someone point me to the right direction. Furthermore I want to draw this with animation.
I am trying to achieve something like this:
Thanks.
