Changes:

• New Feature! Manifold visualizers implement high-dimensional visualization for non-linear structural feature analysis.
• New Feature! There is now a model_selection module with LearningCurve and ValidationCurve visualizers.
• New Feature! The RFECV (recursive feature elimination) visualizer with cross-validation visualizes how removing the least performing features improves the overall model.
• New Feature! The VisualizerGrid is an implementation of the MultipleVisualizer that creates axes for each visualizer using plt.subplots, laying the visualizers out as a grid.
• New Feature! Added yellowbrick.datasets to load example datasets.
• New Experimental Feature! An experimental StatsModelsWrapper was added to yellowbrick.contrib.statsmodels that will allow user to use StatsModels estimators with visualizers.
• Enhancement! ClassificationReport documentation to include more details about how to interpret each of the metrics and compare the reports against each other.
• Enhancement! Modifies scoring mechanism for regressor visualizers to include the R2 value in the plot itself with the legend.
• Enhancement! Updated and renamed the ThreshViz to be defined as DiscriminationThreshold, implements a few more discrimination features such as F1 score, maximizing arguments and annotations.
• Enhancement! Update clustering visualizers and corresponding distortion_score to handle sparse matrices.
• Added code of conduct to meet the GitHub community guidelines as part of our contributing documentation.
• Added is_probabilistic type checker and converted the type checking tests to pytest.
• Added a contrib module and DecisionBoundaries visualizer has been moved to it until further work is completed.
• Numerous fixes and improvements to documentation and tests. Add academic citation example and Zenodo DOI to the Readme.

Bug Fixes

• Adds RandomVisualizer for testing and add it to the VisualizerGrid test cases.
• Fix / update tests in tests.test_classifier.test_class_prediction_error.py to remove hardcoded data.

Deprecation Warnings

• ScatterPlotVisualizer is being moved to contrib in 0.8
• DecisionBoundaryVisualizer is being moved to contrib in 0.8
• ThreshViz is renamed to DiscriminationThreshold.

NOTE: These deprecation warnings originally mentioned deprecation in 0.7, but their life was extended by an additional version.
