Where does the data come from that you can import into dataZoa? The "About dataZoa" page hints at a few of the sources for data that can be used.
A good way to get a feel for the sources of data that contains the dZ-dot is to use the source icon located in the dataZoa toolbar.
After clicking on the icon, a table with source entities apppears. CLick on the + to follow the trail to the dataseries.
