# Introduction to Charts

## Overview

Every [**Variable**](https://help.taglo.io/variables) that you create in Models is automatically visualised for you in a Chart in the [**Variable preview**](https://help.taglo.io/variables/variable-basics#the-variables-preview).

Similarly, if you select multiple related [**Assumptions**](https://help.taglo.io/assumptions), the Assumptions preview will display a chart.

In both of these examples, the Charts can be manipulated (in terms of type of chart, information shown, time periods etc.), allowing you to dynamically investigate your Model's inputs and outputs, but these changes will be temporary, and will be lost when you select other items.

To create permanent visualisations, you can use [**Dashboards**](https://help.taglo.io/dashboards), in which you can view multiple charts in one place.

In either case, and anywhere else that you see a Models chart, the full range of chart customisations will be available to you, which you can read about in the next section.
