What LabVIEW Actually Is
LabVIEW (Laboratory Virtual Instrument Engineering Workbench), from National Instruments (now part of Emerson), is a graphical, dataflow-based programming environment built specifically for test, measurement, and instrument control applications — rather than writing code as text (as in Python, MATLAB, or C), a LabVIEW program (called a "VI," or Virtual Instrument) is built by wiring together graphical function blocks on a canvas, where data flows visually from one block to the next along wires rather than through sequential lines of code. This dataflow model is a genuinely different programming paradigm from the text-based languages covered elsewhere on this site, and it maps particularly naturally onto instrumentation and data acquisition tasks, where the underlying problem really is "data flows from this sensor, through this processing block, to this output" in a way that's visually intuitive to represent as a wired diagram.
