Do you mean you are missing separate maps for each region of South Africa? Currently we only have the country-level map: http://www.highcharts.com/maps/demo/all-maps#countries/za/za-all

I am also facing same problem. I need to use drill down map for South Africa country. Please let me know is it possible to use drill down map for South Africa? As it needed some js file to load drilled map with data and that js file is missing

Do you mean like clicks in one chart will result in changing data in another? Though we don't have a declarative API for it, it is still easy to set up using click handlers and methods like Series.update, Chart.addSeries etc.
