What CS concept should be visualized next?

I launched VizLearn today. It s a visual learning project for algorithms, AI, and computer science.

The thing I m trying to get right is not just show an animation , but letting people change the input and step through what happens.

Right now it has lessons for sorting, data structures, MNIST, backpropagation, attention, scheduling, TCP, and a few more.

If there was one CS topic you always found too abstract, what would you want to see visualized?
