Bubble maps plotted by longitude/latitude - basically a hybrid between mappoints and mapbubbles.
For example, plotting a map of Uganda using the dataset below where the size of the bubble is determined by the datavalue, and the position of the bubble is determined by longitude/latitude.
Longitude | Latitude | City | datavalue

Latitude/longitude support will be available in the upcoming version of Highmaps. It will rely on the proj4 library for projection conversion, and will work with the official Highmaps Map Collection (from v1.1.0 onwards). We will publish documentation on how to make lat/lon work with custom maps once we are ready for release.
For now, the in-development code can be found in the "latlon" branch on github. See these jsFiddles for a preview: http://jsfiddle.net/oysteinmoseng/f97jkgz6/ http://jsfiddle.net/oysteinmoseng/s8yc0cxk/

Currently our featured maps use a custom coordinate system for two reasons:
1. Smaller file size
2. Allow moving of overseas territoriesWe will take a look at how we can resolve the problem of specifying points by longitude and latitude.
