Closes #657

[abbycross]

@kaelynj do you still have this image? -- and if so, would it be complicated to switch the background to light mode? We have functionality to automatically change an image based on the user's light/dark mode preferences.

If and only if we provide the dark mode variant of the image.

The image we have now would serve as the dark mode version -- unless it can't for some reason @Eric-Arellano ?

[kaelynj]

I only have the dark mode version unfortunately. I got it from someone else to make slides from and can ask if they have a light mode version of it.

If we can't get the light-mode version, you can make a rough one by inverting the image, then inverting the hue to preserve the colours.

Thanks for the tip @frankharkins ! I tried out bringing in the image you created and it works to switch from light to dark.

[kaelynj]

These changes look good to me!

Ah, @Eric-Arellano, looks like some of the checks are failing b/c the tox environment does not contain the graphviz library. Is it straightforward to add in/are there any concerns about the prod environment?

It's installed at the OS-level, not Python package manager. So it's more complex than normal but not too bad. You would add graphviz to this line:

documentation/.github/workflows/notebook-test.yml
