I think all charts support setting a custom font style [0]. But: It depends
on the backend which fonts you can actually use. Some defaults are always
supported [1]. I suppose the cairo backend will load all fonts installed in
the system if required, but the diagrams backend only delivers the
defaults. For other or custom fonts in diagrams you need a SVG font version
of the font and pass it into the backend [2]. Shadows are not supported.

Best regards,
Jan
