When To Use It

T3DBarGraph is useful when you want a Delphi-native 3D visualization for dataset-style information, especially when rows, columns, and values have a natural visual relationship.

For very dense datasets, the performance test application is the best place to evaluate whether the 3D representation remains readable for your use case.
