## How is graph theory used today?

Since networks are everywhere, graph theory is everywhere, too. Graph theory is used to model and study all kinds of things that affect our daily lives: from transatlantic shipping routes to integrated circuits, from molecular bonds to animal food webs.

## Why are line plots important?

A line plot is a linear graph that shows data frequencies along a number line. It can be used to analyze data that has a single defined value.

## What can you learn from graphs?

Reading data from graphs Plots of data (and simple relationships between variables) can help geoscientists to understand and predict the physical way that the Earth works. Plotting known data can help us to visualize the behavior of systems in situations that have not been measured.
