Hi, As highlighting a particular region by a specific color is not possible in Geochart, I am extracting countries on region selection from an xml file. ie when South Asia is selected then all the countries and ISO codes will be fetched from an xml file and stored in datatable. Then these cities will be highlighted by a color. The problem is when I select Africa, Its taking time to highlight all the countries. Some countries get selected immidiately but I can visually see some countries getting highlighted one by one. Hence untill all the countries from the datatable dont get highlighted I want to keep a loading indicator. how can I do it?
