t-SNE takes high-dimensional data and reduces it to a low-dimensional graph (1-3 dimensions). Unlike PCA, t-SNE can reduce dimensions with non-linear relationships. PCA attempts to draw the best fitting line through the distribution. T-SNE calculates a similarity measure based on the distance between points instead of trying to maximize variance.
