Okay, so let's imagine that you like to draw things like houses or cars. You want to draw them from different angles, like from the side or from above. But if you just drew them on a piece of paper exactly how you saw them, they might look a little weird.
That's where graphical projection comes in! It's like a special rule or trick to make your drawings look more realistic.
Basically, when you're drawing something in graphical projection, you're pretending that you're looking at it from a really specific point of view. You're imagining that there's a flat screen or piece of paper between you and the thing you're drawing.
Then, you're drawing lines on that screen that show you what you would see if you were actually looking at the thing in real life. This is called a projection, and it makes your drawing look more 3-dimensional and realistic.
There are different types of projections, like orthographic and perspective. They all have different rules and tricks, depending on what angle you want to draw your thing from.
But the most important thing to remember is that graphical projection is like a secret trick that helps you draw things that look more like the real world. It's like wearing special glasses that make everything look cooler!
