Here is a proposal of what could become the orientation page on how to use charts, with a couple of options open for debate. Before considering more visuals and making the tables more appealing, I'd like to check with you if this is going in the right direction.
Option A -- reflects the decision tree that Giovanni started in this Figma, but it doesn't cover all the available charts.
Option B -- offers hints on "when to use what" and lists all the available charts.

@alaudazzi the decision tree from Gio doesn't translate well to the table format. I would say we either keep the decsion tree or if we need the table, then we move to your Option B. But Option B is a bit difficult to consume, I guess we are adding some examples with images.
