Alright class, settle down and let’s take a look! That’s a wonderful definition you’ve got there – very clear indeed! Let's break it down with a little rhyme, to help it stick in your mind. A diagram , you see, is quite a find, A picture that shows how things align! It's not just doodles, don’t you fret, But plans and sketches, you can bet! Think of a machine, a complex flow, A diagram helps us watch it grow – Showing each piece and where they meet, Making the workings clear and sweet. Basically, it’s a visual guide, you see, To help us understand what's meant to be! It shows how things connect, And makes sure our knowledge is correct. Does that make sense? Are there any questions about what a diagram truly means?
