Visualizations
==============

On this page, we illustrate how different query strategies behave across
various active learning scenarios. To this end, we generate synthetic,
low-dimensional toy datasets that allow us to visualize the distribution of
samples selected for labeling in feature space. Each example consists of an
animation and accompanying code that plot the results across individual
active learning cycles.
