update bubble chart text

[jkoschinsky]

Change interpretation text for bubble chart (see Linkedin video part 2, 1:54):
“The spatial distribution of bubbles …” —> The location of bubbles in the scatter plot

This interpretation text is generated by LLM and it might be different every time when running this function (see https://platform.openai.com/docs/guides/text-generation/how-should-i-set-the-temperature-parameter). I can't change it specifically, however, I can try to add it as a restriction (e.g. use "the location of bubbles" to replace "the spatial distribution of bubbles") in the instruction for our assistant model.
