Qt Data Visualization

Qt Data Visualization module provides a way to visualize data in 3D as bar, scatter, and surface graphs. It is especially useful for visualizing depth maps and large quantities of rapidly changing data, such as data received from multiple sensors. The look and feel of graphs can be customized by using themes or by adding custom items and labels to them.

Qt Data Visualization is built on Qt 5 and OpenGL to take advantage of hardware acceleration and Qt Quick 2.
