The back panel, which is a block diagram, contains the graphical source code. Indicators are outputs: they indicate, or display, the results based on the inputs given to the VI. Controls are inputs: they allow a user to supply information to the VI.

The front panel is built using controls and indicators. The last is used to represent the VI in the block diagrams of other, calling VIs. Each VI has three components: a block diagram, a front panel, and a connector pane. LabVIEW programs-subroutines are termed virtual instruments (VIs). LabVIEW integrates the creation of user interfaces (termed front panels) into the development cycle. : 1–2 Multi-processing and multi-threading hardware is exploited automatically by the built-in scheduler, which multiplexes multiple OS threads over the nodes ready for execution. Since this might be the case for multiple nodes simultaneously, LabVIEW can execute inherently in parallel. These wires propagate variables and any node can execute as soon as all its input data become available.

Execution flow is determined by the structure of a graphical block diagram (the LabVIEW-source code) on which the programmer connects different function-nodes by drawing wires. If there is enough data available to a subVI or function, that subVI or function will execute. The programming paradigm used in LabVIEW, sometimes called G, is based on data availability. NI released the free for non-commercial use LabVIEW and LabVIEW NXG Community editions on April 28th, 2020. The latest versions of LabVIEW are LabVIEW 2021 SP1 (released in February 2022) and LabVIEW NXG 5.1 (released in January 2021).

The G dataflow language was originally developed by LabVIEW, LabVIEW is commonly used for data acquisition, instrument control, and industrial automation on a variety of operating systems (OSs), including Microsoft Windows as well as various versions of Unix, Linux, and macOS. The graphical language is named 'G' not to be confused with G-code. Laboratory Virtual Instrument Engineering Workbench ( LabVIEW) : 3 is a system-design platform and development environment for a visual programming language from National Instruments.
