# Nodes 101
It's all about them
## What are Nodes?
**Nodes are the building blocks of your visuals.** Each node performs a specific function — generating shapes, processing data, applying effects, or outputting values.
## **Graph**
When you connect nodes they form a **graph** — a visual network that defines how your project operates.
The result you see in the **Render View** is the live output of that graph — Every frame is rendered based on its current state and connections. In other words, what you build in the graph, is exactly what drives the visuals you see.
