Jubilat and Campaign Grotesk are the typefaces used for the Plotly website. The technical computing company from Montréal, Canada develops online data analytics and visualization tools. Plotly is probably best known for its products Dash and Charts Studio.
Jubilat by Darden Studio serves in Regular and Medium weights. The modulated slab serif is specified for large and medium-sized texts, from headings and subheadings to teasers, pull quotes, and figures in infographics and a timeline. Jubilat is economically spaced, with tight fitting and compact extenders, and yet its letterforms aren’t condensed. This characteristic makes it a formidable match for Campaign Grotesk with its wide proportions. The idiosyncratic grotesque by PSTL is used for all smaller text.
