**Note:** It is important to note that any figures containing WebGL traces (i.e. of type `scattergl`, `heatmapgl`, `contourgl`, `scatter3d`, `surface`, `mesh3d`, `scatterpolargl`, `cone`, `streamtube`, `splom`, or `parcoords`) that are exported in a vector format will include encapsulated rasters, instead of vectors, for some parts of the image.

### Install orca on Google Colab
```
!pip install plotly>=4.7.1
!wget https://github.com/plotly/orca/releases/download/v1.2.1/orca-1.2.1-x86_64.AppImage -O /usr/local/bin/orca
!chmod +x /usr/local/bin/orca
!apt-get install xvfb libgtk2.0-0 libgconf-2-4
```

Once this is done you can use this code to make, show and export a figure:
<!-- #endregion -->

```python
import plotly.graph_objects as go
fig = go.Figure( go.Scatter(x=[1,2,3], y=[1,3,2] ) )
fig.show()
fig.write_image("fig1.svg")
fig.write_image("fig1.png")
```

The files can then be downloaded with:

```python
from google.colab import files
files.download('fig1.svg')
files.download('fig1.png')
```

### Get Image as Bytes
The `plotly.io.to_image` function is used to return an image as a bytes object. You can also use the `.to_image` graph object figure method.
