This PR adds a new file formats.typ that defines some tick formatters.

  • fraction: Formatting tick labels as fractions
  • multiple-of: Formatting tick labels as a multiple of a constant (e.g. pi)
  • sci: Scientific number formatter

I've changed the "lines" gallery entry to some better looking one that show approximations of sin x and uses the new functions.

Idk. about this. It is the simplest solution I came up with and I think if you really want other fractions, it is fine requiring specifying a fixed denominator.

Is there a reason for 11 + 1 instead of 12?

To highlight that, we generate fractions up to n/11, not 12 (because range being zero-based).

This looks good to me. Perhaps for a separate PR, it might be worth adding another tick formatter that places the exponent at the top of an axis like so

But this is a nice PR :)
