A graph-based user interface for openDAQ.

• Great for overviews of complex dataflows
• Responsive user interface with immediate feedback
• Edit properties of multiple components at once
• Automatic signal plotting for selected components
• Quick signal previews on hover
• Simple connecting and disconnecting of signals
• Trivial adding of nested function blocks or devices
• Color-coded components based on their parent device
• Errors and warnings discoverable at glance

Prebuilt binaries are available for 64 bit Windows and Linux, on other platforms you will need to build the project from source. The prebuilt binaries come with reference function blocks and devices from openDAQ.
