# 1 Graphs

#### Overview

With lots of data flowing into Zabbix, it becomes much easier for the
users if they can look at a visual representation of what is going on
rather than only numbers.

This is where graphs come in. Graphs allow to grasp the data flow at a
glance, correlate problems, discover when something started or make a
presentation of when something might turn into a problem.

Zabbix provides users with built-in [simple
graphs](/manual/config/visualisation/graphs/simple) as well as with the
possibility to create more complex [customised
graphs](/manual/config/visualisation/graphs/custom).
