The Glg Toolkit is a RAD tool for developing dynamic data-driven C/C++ or 100% pure Java graphics and visual components: from simple animations to process control, satellite telemetry, mission control and other applications which require visualizing real-time data.

It includes an interactive point-and-click Graphics Builder for creating 2D and 3D dynamic graphics displays, and a C/C++ or 100% pure Java class library with a Java Bean interface for embedding the graphics into programs. Prebuilt sets of 2D and 3D graphs, dials, meters and other widgets are also available.
