Question

There are multiple ways to load data into the controller of Gio.js. The basic way is to use
addData API. To load data asynchronously, use addDataAsync
API. To refresh the data
periodically, you can use liveLoad API. To clear data in globe, use clearData API. To make a better visualization of data flow, the range of
the data is adjusted before used for rendering. To do a fine-grained control over the color of each line
that connects two countries, check set line color from data. You can also
add a data group to controller, and use switchDataSet API to switch
between different data sets in this data group. Data can also been exported to Continent.
