Hilbert curve

A Hilbert Curve is a special type of line that twists and turns in a very complicated way like a long winding snake. Think of it like a squiggly line formed by connecting a bunch of really tiny squares together. The interesting part about the Hilbert Curve is that it can fit perfectly inside any size square or rectangle. This means no matter how big the square or rectangle you start with, the Hilbert Curve will always fill the whole shape without leaving any gaps. It’s like magic!
