From looking at the screen, it reads on the left side (next to hand) on the axis: "Angry, Passionate, Happy, Animated, Curious..." and so on. The other axis is very tough to get any sort of guess. Some look like music genres, others look like different metrics that would be measured by a graph. My guess would be that this was made up by Apple to showcase the Pro's better array of colors and allow for a nice looking landing page for their website. I may be wrong, but from this image, it doesn't look like it's an app. If it is, it looks like it'd be data collection or chart creation, just my guess though!
