Tidier is an organization dedicated to crafting a data analysis and visualization ecosystem in Julia inspired by the tidyverse in R. Our flagship package is Tidier.jl, a 100% Julia implementation of the R tidyverse meta-package. Tidier.jl wraps best-in-class Julia data analysis packages like DataFrames.jl and Makie.jl to bring the best of both worlds: convenient syntax and blazing fast speed.

Over the course of this brief talk, we hope to demonstrate how Tidier is a great tool for broad variety data analysis/tasks needs and touch on some of the design choices, guiding principles and goals.

(+one exciting resource that will hopefully be up)
