[02-space_stretching.ipynb] Color pattern for show_scatterplot

[aeryskyB]

Hi!

I saw your lecture and came here expecting the updated colors.
But, it was not updated.
So, I tried tweaking things on my own.
However, the result turned out a little bit weird!

It doesn't look the same. TT

Is there any possibility for future updates?
Or should I make a PR?

Best!

Haha, you're right. I should push an update (which is way overdue).
I made it work by querying the colour from this scheme.

Thanks for sharing the coloring scheme, and the update...

Best wishes...^^

Students asked me to do this for the last 8 semesters 🥲
You're welcome. Thanks for opening the issue.
