Five ggplot2 functions I wish I’d known about earlier – Nicola Rennie
There are a few small tweaks you can make to your ggplot2 code to improve your charts. However, they’re not often mentioned. So here’s a few functions and arguments I wish I’d known about earlier.

Late for #Day8 of the #30DayChartChallenge, but the "Circular" prompt is the perfect excuse to share yet another #ggplot2 trick! 👀 Tried the "new" #coord_radial yet? Compared to coord_polar, it: 🌀 bends grid lines 🌀 places labels naturally 🌀 allows inner radii 🌀 handles partial circles easily

A three-panel chart showing the distribution of renewable electricity share across countries in 2022 at three scales. Panel 1 is a histogram of the global distribution, revealing a bimodal shape with many countries clustered near 0–20% and another group near 100%, with a median of roughly 32%. Panel 2 shows half-eye density plots by World Bank income group — Low, Lower-middle, Upper-middle, and High — all with similar medians around 28–36%, but notably different spreads and shapes. Panel 3 zooms in on Upper-middle income countries as a dot plot, where individual-country variation is stark: South Africa sits near 0%, China and Turkey near 25–30%, and Brazil and Paraguay near 80–100%.

Map of Earth setting behind the moon, with Australia the lone visible landmass. The lunar surface is faded, but visible.Earth setting behind the moon, with coastline overlain. Australia is the lone visible large landmass.The lunar surface fills the frame in sharp detail, as seen during the Artemis II lunar flyby, while a distant Earth sets in the background. This image was captured at 6:41 p.m. EDT, on April 6, 2026, just three minutes before the Orion spacecraft and its crew went behind the Moon and lost contact with Earth for 40 minutes before emerging on the other side.
 
In this image, the dark portion of Earth is experiencing nighttime, while on its day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater shows terraced edges and a relatively flat floor marked by central peaks — formed when the surface rebounded upward during the impact that created the crater.Map of Earth setting behind the Moon from the perspective of Artemis II.

#30DayChartChallenge Day 2 : Pictograms (erratum version, see thread) ⚠️🦊🐦🐸🐌🌿🍄⭐🦎🐛 This chart shows how many species are considered threatened in #Canada, broken down by major taxonomic group (mammals, birds, amphibians, plants, etc.), according to the IUCN #RedList. #Rstats #dataviz #wildlife
This chart shows how many species are considered threatened in #Canada, broken down by major taxonomic group (mammals, birds, amphibians, plants, etc.), according to the IUCN Red List.

Title : How many species are threatened in Canada?
Subtitle : The count in each major taxonomic group, according to the Red List.
The entire image has a red background with everything else in white (text, labels, data points etc).
 
The chart is a circular pictorial plot, using aspecific pictogram for each taxonomic group. There's Amphibians, Reptiles, Mammals, Molluscs, Plants, Fungi, Birds, Other Inverts, Fishes. At the center there is a frog, representing the Amphibians, it's alone as there is only one species of Amphibian that is threatened. It then extends to 5 pictograms for reptiles and then goes all the way to fishes which are the largest group in terms of threatened species, for a count of 52 species.

The source is The IUCN Red List of Threatened Species
