A little bit of #DataArt on a Monday afternoon! 
Can you guess the data? 
The data is from this week's #TidyTuesday! The data looks at publications that explore racial and ethnic disparities in reproductive healthcare. This mosaic/Marimekko chart shows how the number of publications changes over time, as well as the study types used.
Code: https://github.com/nrennie/tidytuesday/tree/main/2025/2025-02-25
There are also lots of beautiful examples of data art by college students at Amherst College, created to raise awareness about this research: https://katcorr.github.io/this-art-is-HARD/
@nrennie TIL what a "Marimekko" chart is and why it's called that (named after a Swedish design company?). (I think I'll stick with "mosaic plot" — might have changed if Marimekko were a person/original designer.)
But also, what package(s) did you use for this plot?
@ryanmcshane Yes, Marimekko charts are another name for mosaic plots since they can look like some of the prints created by the Finnish textile company of that name. (TIL the company name comes from a combination of the founder/designer's middle name and the Finnish word for dress).
This chart is just made with geom_col() in {ggplot2}, although there is a {ggmosaic} package that could probably make it as well. Code is here: https://github.com/nrennie/tidytuesday/tree/main/2025/2025-02-25
OK {ggplot2} `geom_col` with `theme_void` was my guess! Thanks for confirming.
There's also the built-in {graphics} `mosaicPlot`, but it doesn't look this nice! It's the gaps.
@nrennie @ryanmcshane
Surprisingly hard to find a picture of a Marimekko product that looks like a Marimekko chart, but I found this in the end. I wasn't able to find out who designed it.
@ryanmcshane @nrennie Yes :) That kind of Marimekko textile must have been really popular at some point in time, to inspire the naming of the chart. Marimekko is still very famous but not for that kind of pattern (but for instance for Maija Isola's "unikko" flowers)
