DataCogs uses Panels to organize your workspace. Panels are similar to windows. They can be tiled or tabbed together, and you can resize them and move them around to suit your workflow.
Applets are the building blocks of DataCogs. They are small programs that run inside Panels. Applets can be used to view and interact with data, run code, or create visualizations. Some of the built-in Applets include the File Browser, Graph, and Text Editor.
In the top-right corner of the DataCogs window, you'll find the Applet Bar. The Applet Bar contains buttons for opening Applets.
