I just tried to recreate your example in Gemini and got this, took about 20 seconds to do could change the axis labels as well if you needed it to?

Thanks to @joel120193.bsky.social today I used notebook lm to create audio feedback in the form of a podcast to a student on the test they had completed, really excited to get the students trained on this now #edusky

This looks great just got it to create an article on formative assessment that would be extremely useful for onteavour trainee teachers, thanks
