• scatter_matrix (deprecate, redirect to seaborn)
• andrews_curve
• parallel_coordinates
• lag_plot (maybe rename to lag)
• autocorrelation_plot (maybe rename to autocorrelation?)
• bootstrap_plot (maybe rename to bootstrap?)
• radviz

I think it would be nice to allow scatter_matrix to be called directly on a DataFrame. Currently, scatter_matrix is a separate function that takes a DataFrame as a parameter, but it seems like it would be easy enough to rework to allow it to be called directly on a DataFrame as well. Effectively, the convenience function would look something like:

def scatter_matrix(self, ...):
    pandas.tools.plotting.scatter_matrix(self.data, ...)

Is this feature feasible?
