This thread is so great! 🤩 To avoid annoying resizing, figured I'd mention an alternative to {ggview}: {showtext} can resize all text to a specific dpi Text is the part that I find I have to fiddle with most when saving #ggplot2 plots, so this usually works for me 😀 #rstats #dataviz

library(showtext) showtext_opts(dpi = 300) ggsave( plot = my_plot, file = "file_name.png", width = 6, height = 4, dpi = 300 )

If you missed today's @rinpharma.bsky.social workshop, here are a few of my favourite "quick fixes" for some common #ggplot2 issues 📊 1. Use {ggview} to preview plots at the same size and resolution as you want to save them with ggsave() to avoid the annoying resizing #RStats #DataViz

library(ggview) ggplot(mtcars, aes(wt, mpg)) + geom_point() + canvas( width = 6, height = 4, units = "in", dpi = 300 )

3 decades of data 😮 on this fairy-wren population showed how many cumulative effects of climate change (lower food supply, chick rearing, higher pesticides) can lead to population decline, even for a species categorised as “least concern” on the IUCN Red List 🥺 🌏🧪🦜 news.mongabay.com/2026/08/supe...

Superb fairywrens disappearing in Australia’s capital: Conserving insects could help save them

If you sit in an Australian park or garden for long enough, chances are you might catch a flash of brilliant feathers out of the corner of your eye: the superb fairywren. With its bright blue and soft...

Cultural knowledge + Western data on one canvas! 🖌️ That's the idea our recent intern Gullara McInnes and her mother Ann-Marie Keating had. The result: This incredible painting of biodiversity in their local area featuring occurrence data from the Atlas of Living Australia 🧪🌏📊 #NationalScienceWeek

A painting by Ann-Marie Keating and her daughter Gullara McInnes depicting animals and plants in Mareeba, a rural town near Cairns, Australia. The painting has a black border, and inside there are over 60 species of animals and plants painted using many different painting techniques. Traditional dot art is used on each species to show the number of observational records on the Atlas of Living Australia, Australia's largest data infrastructure of biodiversity data.

🐌 How much data do we have of our slimy snail & slug friends? How many species do we know virtually nothing about? Despite having over 1.5 million observations of gastropods in Australia, many species have fewer than 10 records, or no records at all 😯 Code & high-res 📷 👇 🧪🌏📊 #rstats #dataviz

A waffle bar chart showing the taxonomic coverage of gastropod records in the Atlas of Living Australia. The plot shows the number of species in each gastropod suborder with 100+ records, 10+ records, 1+ records or no records at all. In general, there is quite a high proportion of species (between 13% and 36% depending on the group) with fewer than 10 records or no records at all. The waffle chart consists of squares in different shades of purple to show species record count. Each group is shown in a separate bar. The background is a very dark purple. Example images of snails from each suborder group are shown below each bar.

Whoa when this invasive mushroom grows on a dead or dying hardwood tree, the fungal diversity of that tree is cut in half (on average) 😯🍄 Spreading across the US & Canada as well as Switzerland, Italy, Hungary, Serbia & Germany, this fungus could have a huge cascading impact on global ecosystems 🧪🌏

If it didn't make bright yellow mushrooms, we probably wouldn't even know golden oyster was reducing fungal diversity on decaying hardwoods worldwide. A very interesting genetic banking endeavor to conserve imperiled native fungi whose ecosystem roles we certainly don't understand yet. 🍄🧪

Awesome dataviz 🤩 So interesting how much variation there is in phrases like "Realistic possibility" compared to "About even" No wonder it's so difficult to use experimental survey data as strong evidence in research. People are too varied at interpreting scales! 🧪 #psychscisky

Nicola Rennie@nrennie.bsky.social · 8mo ago

A really fun dataset for this week's #TidyTuesday, looking at how people interpret different probabilistic statements 📊 There's so many aspects of this to visualise, but I decided make some barcode plots comparing how people from the UK and US responded! #DataViz #RStats #ggplot2

Mirrored bar plot showing the distribution of estimated probabilities for different terms, for US and UK respondents. Will happen is ranked most likely, and almost no chance is least likely. Points highlight the median which are identical for both groups except for may/might happen and highly likely where US medians are higher.

A nice visual, and a worthwhile one to remember when considering gaps and biases in biodiversity data in Australia 🦘🌱 Nearly 70% of the population lives in a greater capital city, meaning that incidental observations of animals and plants outside of those areas are rare and valuable 🧪🌏📊

Love these population density spike maps. (by @researchremora) www.kontur.io/solutions/au...

This population density map of Australia visualizes how most of the population is concentrated in coastal cities like Sydney, Melbourne, Brisbane, and Perth. The interior is mostly uninhabited, with labels like "NO ONE LIVES HERE" emphasizing the vast emptiness. The vertical spikes represent population density, showing the stark contrast between urban centers and the sparsely populated outback.
