#### 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/visualization/graphs/simple)
    of one item data
-   the possibility to create more complex [customized
    graphs](/manual/config/visualization/graphs/custom)
-   access to a comparison of several items quickly in [ad-hoc
    graphs](/manual/config/visualization/graphs/adhoc)
-   modern customizable vector [graphs](/manual/web_interface/frontend_sections/dashboards/widgets/graph) 
and [pie charts](/manual/web_interface/frontend_sections/dashboards/widgets/pie_chart)
