-inspect3d provides a number of ways to visualize and interact with the results of pca. an overview of all pca visualizes can be found in [[inspect3d:documentation:pages:pca_graphs|inspect3d pca graphs]].
-this page includes:
-  * visualizing the [[inspect3d:documentation:pages:pca_graphs#variance_explained|variance explained by each pc individually]];
-  * visualizing the [[inspect3d:documentation:pages:pca_graphs#loading_vector|variance explained by each pc at each point in the signal's cycle]];
-  * [[inspect3d:documentation:pages:pca_graphs#subject_scores|scatter-plotting workspace scores]] in pc-space;
-  * showing the [[inspect3d:documentation:pages:pca_graphs#group_scores|distribution of scores by group]] for each pc;
-  * visualizing the [[inspect3d:documentation:pages:pca_graphs#extreme_plot|mean and extreme values]] that result from reconstructing the underlying data with each pc; and
-  * visualizing how the signals can be [[inspect3d:documentation:pages:pca_graphs#pc_reconstruction|reconstructed from the computed pcs]].
