Presage Group presentation at JuliaCon 2025

Presage was represented by Randy Boyes at Juliacon in Pittsburg for the second year as part of our continuing support for open source data analysis. Randy presented the recent developments in TidierPlots.jl, a ggplot-inspired package for data visualization in Julia.

Key developments

TidierPlots.jl has two new computation systems, one that uses DataFrames.jl and one that relies on TidierData.jl.

aes(x = :x => x -> x/10) # DataFrames-style
@aes(x = x/10)           # TidierData-style

New scales, including scale_fill, scale_alpha, and more have been added, along with support for facet_grid. More detail is available in the slide deck and presentation linked below!
