Akima spline

Okay, so you know when you draw a line or a curve on a piece of paper, right? And sometimes you want to make it look really smooth, without any bumps or jumpy parts. That's where something called a spline comes in.

An Akima spline is a special way of making a really smooth curve that goes through a bunch of different points. It's like putting a bunch of dots on a piece of paper and then drawing a line that touches all the dots but stays really smooth and curvy in between them.

The way an Akima spline works is kind of like magic! It uses some fancy math to figure out how to connect all the dots in the smoothest, most curvy way possible. It looks at the neighboring dots on either side of each point and tries to make the curve go as smoothly as possible from one point to the next.

So basically, an Akima spline is like a magic trick for making really smooth curves that go through a bunch of different points. It's something that smart people use to make things look really nice and polished!
