I am using highmaps to display data segmented by countries. It works nice but I have an issue I'm not sure how to approach.
I need to group some countries of Central America and Venezuela together in the world-map and show them as one single country. This grouping could change in time so it would be nice to be able to do it programmatically. I tried passing an array in the joinBy field of that concrete point but it does not work and neither the documentation or examples mention anything about what I'm trying to accomplish.
How would you guys do it?
