Types of Line Graphs
1. Simple Line Graph
Shows one variable changing over time (like the temperature example above).
2. Multiple Line Graph
Compares two or more variables on the same graph. Each line represents a different dataset.
3. Step Graph
Shows data that changes in distinct steps rather than smooth transitions. Useful for things like postage rates or tax brackets.
4. Smooth Curve
When data points suggest a smooth mathematical relationship, the line may be curved rather than straight between points.
