From the developer:
NChart3D is a universal charting framework for data visualization. Multiple chart types, 2D & 3D, excellent lighting effects and smooth animations make your data look gorgeous. The visual appearance of the chart elements is fully customizable. You can use solid colors, gradients and even textures (for 3D models). Each element - like caption, legend, tooltip, etc. - of the chart is customizable.
