Alloys that are comprised of more than 50% of a particular element are colored accordingly. Alloys that do not have a majority element are colored in gray. Diagonal rows depict property distributions for each class of alloy. The lower-left triangle depicts Kernel Density Estimate (KDE) estimates over joint property distributions to better visualize the structure of the data.
