From dataZoa Wiki
The first pair of tools are about getting data from external sites on the World Wide Web. The drop target is the spot where you release data series links that your are dragging into dataZoa. The global index opens an index to a huge variety of data sources.
The second pair of tools are used to upload and edit your own data series.
Finally, the push pin represents the dZCorkboard, a handy way to maintain your series, whatever their origins.
