Returns the explanation as an html page.

        Args:
            labels: desired labels to show explanations for (as barcharts).
                If you ask for a label for which an explanation wasn't
                computed, will throw an exception. If None, will show
                explanations for all available labels. (only used for classification)
            predict_proba: if true, add  barchart with prediction probabilities
                for the top classes. (only used for classification)
            show_predicted_value: if true, add  barchart with expected value
                (only used for regression)
            kwargs: keyword arguments, passed to domain_mapper

        Returns:
            code for an html page, including javascript includes.
