JSon Problem

Yes, several, but it really depends on what that image represents and what you intend to do with it.

A simply static image: QPainter::drawLine() and QPainter::drawRect()
A 2D image over which other 2D objects can be placed: QGraphicsView and QGraphicsScene
A 3D plane grid on which 3D objects should be placed: QOpenGLWindow and OpenGL functions

Thanks for the info. Do you have any tutorial site or helpful links that can help us to create 3D checkboard.
