How it works...
The OneVsRestClassifier creates many binary SVC classifiers: one for each class versus the rest of the classes. In this case, three decision boundaries will be computed because there are three classes. This type of classifier is easy to conceptualize because there are fewer decision boundaries and surfaces.
If there were 10 classes, there would be 10 x 9/2 = 45 surfaces if SVC was the default OneVsOneClassifier. On the other hand, there would be 10 surfaces for the OneVsAllClassifier.
