The class :class:`autonlu.data_dependence.DataDependence` can be used
to visualize the relationship between the amount of training data and
the accuracy of the resulting model. This information can be used to
determine whether labeling additional data is probably going to be
useful or not.

Here an example for a case where additional training data is likely
not going to improve the resulting model (note that the x axis has a
logarithmic scale):
