A graph is a pictorial representation of data, which has at least dimensional relationship.

A graph is a pictorial representation of data that displays the relationship between variables using visual elements like points, lines, or bars.

For any graph to meaningfully represent data, it requires at least two dimensions:

1. X-axis (Horizontal) - Represents one variable (typically the independent variable)
2. Y-axis (Vertical) - Represents another variable (typically the dependent variable)

Even the simplest graph, such as a bar chart or line graph, needs both axes to show how one variable relates to another. Without two dimensions, we cannot establish a relationship between variables pictorially.

While graphs can have more dimensions (3D graphs or even 4D with time/color), the minimum requirement is 2 dimensions to establish a relationship.
