# How to use graphs | ||
|
||
This guide shows you how to use graphs to visualize your data in the dashboard. | ||
|
||
The [`Page`][vizro.models.Page] models accepts the `components` argument, where you can enter your visual content e.g. | ||
[`Graph`][vizro.models.Graph], [`Table`][vizro.models.Table], [`Card`][vizro.models.Card] or [`Button`][vizro.models.Button]. | ||
|
||
## Graph | ||
|
||
The [`Graph`][vizro.models.Graph] model is the most used component in many dashboards, allowing you to visualize data in a variety of ways. | ||
|
||
To add a [`Graph`][vizro.models.Graph] to your page, do the following: | ||
|
||
- insert the [`Graph`][vizro.models.Graph] model into the `components` argument of the | ||
[`Page`][vizro.models.Page] model | ||
- enter any of the currently available charts of the open source library [`plotly.express`](https://plotly.com/python/plotly-express/) into the `figure` argument | ||
|
||
!!! note | ||
|
||
In order to use the [`plotly.express`](https://plotly.com/python/plotly-express/) chart in a Vizro dashboard, you need to import it as `import vizro.plotly.express as px`. | ||
This leaves any of the [`plotly.express`](https://plotly.com/python/plotly-express/) functionality untouched, but allows _direct insertion_ into the [`Graph`][vizro.models.Graph] model _as is_. | ||
|
||
|
||
|
||
!!! example "Graph" | ||
=== "app.py" | ||
```py | ||
import vizro.models as vm | ||
import vizro.plotly.express as px | ||
from vizro import Vizro | ||
|
||
df = px.data.iris() | ||
|
||
page = vm.Page( | ||
title="My first page", | ||
components=[ | ||
vm.Graph( | ||
id="my_chart", | ||
figure=px.scatter_matrix( | ||
df, dimensions=["sepal_length", "sepal_width", "petal_length", "petal_width"], color="species" | ||
), | ||
), | ||
], | ||
controls=[vm.Filter(column="species", selector=vm.Dropdown(title="Species"))], | ||
) | ||
|
||
dashboard = vm.Dashboard(pages=[page]) | ||
|
||
Vizro().build(dashboard).run() | ||
``` | ||
=== "app.yaml" | ||
```yaml | ||
# Still requires a .py to register data connector in Data Manager and parse yaml configuration | ||
# See from_yaml example | ||
pages: | ||
- components: | ||
- figure: | ||
_target_: scatter_matrix | ||
color: species | ||
data_frame: iris | ||
dimensions: ["sepal_length", "sepal_width", "petal_length", "petal_width"] | ||
id: my_chart | ||
type: graph | ||
controls: | ||
- column: species | ||
type: filter | ||
selector: | ||
title: Species | ||
type: dropdown | ||
title: My first page | ||
``` | ||
=== "Result" | ||
[![Graph]][Graph] | ||
|
||
[Graph]: ../../assets/user_guides/components/graph1.png | ||
|
||
Note that in the above example we directly inserted the chart into the `figure` argument for the `.py` version. This is also the simplest way to connect your chart to a Pandas `DataFrame` - for other connections, please refer to [this guide on data connections](data.md). For the `yaml` version, we simply referred to the [`plotly.express`](https://plotly.com/python/plotly-express/) name by string. | ||
|
||
|
||
??? info "Vizro automatically sets the plotly default template" | ||
|
||
When importing Vizro, we automatically set the `plotly` [default template](https://plotly.com/python/templates/#specifying-a-default-themes) to | ||
a custom designed template. In case you would like to set the default back, simply run | ||
```py | ||
import plotly.io as pio | ||
pio.templates.default = "plotly" | ||
``` | ||
or enter your desired template into any `plotly.express` chart as `template="plotly"` on a case-by-case basis. | ||
Note that we do not recommend the above steps for use in dashboards, as other templates will look out-of-sync with overall dashboard design. |
