OpenGraph Library (SDK)


OpenGraph Library (SDK) is a powerful 2D and 3D visualization and charting software tool on x64 and x86 Windows. It is built on the industrial strength OpenGL. The library shields you from the need to learn the complex OpenGL API, and makes it easy to setup impressive and interactive graphics such as zooming, panning, selecting, etc. This library is especially suitable for building scientific, engineering, and financial software applications.

What our clients are saying:

I am working on visualization of large graphs and dynamics graph. Visualization of dynamics graphs is big challenge now. Visualization of large and dynamics graph is very useful approach to understand information which is hidden in Big data. OpenGraph Library is very useful for it. It can speed up my research.
