I typically run a PCA then use the scores of PCA to run SVM classification and plot the decision boundaries based on that. I know the results will be somewhat different from the SVM only approach, however it can show you some rough idea about the structure of data and its relationship to the decision boundaries.

Subject: Plotting Data
I am using a SVM toolbox. if we want to use SVM to classify two classes
data, it is very straight forward to plot the data, if the number of
elements in the input vector is equal to 2.
but what if the number of elements in the input vector is equal to 3 or 4
or even 10 or even 100, how we are gonna be able to plot that,
another issue, the toolbox i am using they only deals with two elements in
the input vector, what if wewant to consider more than two elements would
we be able to perform that.
thank you very much for your help in advance
