Type 1 fonts in Plotly

Does anyone know if Plotly uses type 1 fonts by default? Otherwise, is there a way to use a type 1 font in a figure?

I’m hoping to include a Plotly plot in one of my research papers and the venue I’m publishing to requires all figure text to have type 1 fonts. However, I cannot find out if Plotly uses Type 1 fonts are not (Although, this maybe the wrong question given I don’t quite understand the distinctions between typed fonts).

I would appreciate it if anyone can help me out with this question.
