The block diagram contains the graphical source code of a LabVIEW program. The concept of the block diagram is to separate the graphical source code from the user interface in a logical and simple manner. Front panel objects appear as terminals on the block diagram. Terminals on the block diagram reflect the changes made to their corresponding front panel objects and vice versa.

Block Diagram Objects and Environment
Block diagram objects include terminals, subVIs, functions, constants, structures, and wires that transfer data among other block diagram objects. You can use LabVIEW tools to create, modify, and debug a VI. A tool is a special operating mode of the mouse cursor, so the operating mode of the cursor corresponds to the icon of the tool selected. LabVIEW chooses which tool to select based on the current location of the mouse. You can manually choose the tool you need by selecting it on the Tools palette (from the menu bar, select View» Tools Palette). Now you can choose your desired tool, which remains selected until you choose another tool from the Tools palette.
VI Toolbar - Use the buttons on the VI toolbar to run VIs, pause VIs, abort VIs, debug VIs, configure fonts, and align, group, and distribute objects.
