All roads lead to Rome?

Well, here’s a map to check that saying.

The prompt for day 12 of the #30DayMapChallenge is a "map from 2125", and this one *almost* fits that description! This shows the areas of Scotland likely to be affected by coastal erosion by 2100 🗺️

#RStats #ggplot2 #DataViz
Map of Scotland with white areas around the coast highlighted. White areas are around most of the coast, though Orkney looks especially affected.

tmap or ggplot2 for maps? 🗺️

tmap vs. ggplot2 for mapping – Geospatial Stuff
For me at least the choice between ggplot2 and tmap is an ongoing question. Here are my latest thoughts on the subject (with code).

It's Day 10 of the #30DayMapChallenge and for the "air" prompt, I decided to look at air quality data before and after Bonfire Night in the UK 🎇

#RStats #ggplot2 #DataViz
Side by side maps of the UK showing air quality before and after Bonfire night. The day after Bonfire night shows many more sites marked as exceeding a threshold of 40 micrograms/m3.

This week's #TidyTuesday data is from the WHO and looks at rates of TB cases and deaths around the world 📊

I used the {ggh4x} package to get this custom facet layout with large chart for global data, and then small multiples for each WHO region 🗺️

#DataViz #ggplot2 #RStats
Small multiple area plots showing TB cases and deaths from 2000 to 2023. Large plot shows the global rates, with mostly downward trend before a slight increase around 2020. Small version of the plot breakdown the same figures for different WHO regions, with Africa and South-East Asia highest, and recent increases seen in South-East Asia and the Western Pacific.

How long does it take your kid to get to their secondary school in Cologne?

It depends on where you (and your child) live and what type of secondary school your child attends. (Path times to the nearest school by bike.)

#30DayMapChallenge | Day 03 - Polygons #rstats #ggplot2
A map which shows the path times by bike to the nearest school for 4 secondary school types from each point within Cologne: Gymnasium (academic secondary school), Gesamtschule (comprehensive school), Realschule (intermediate secondary school), Hauptschule (secondary general school). The academic secondary schools are found closer to the city center compared to other school types.

#rstats | #r4ds | #dataviz | #ggplot2
Line chart showing HIV-associated TB deaths as percentage of total TB mortality by WHO region from 2000-2024. Africa's bold blue line dominates, declining from 60% to 28% (31.9 percentage point decrease). Five other WHO regions shown in gray remain below 35% throughout, with most under 15%. All regions labeled at right endpoint. Chart demonstrates Africa's significant progress yet persistent disproportionate burden of HIV/TB co-infection.

For the "accessibility" prompt on day 7 of the #30DayMapChallenge, I decided to investigate how accessible the default #ggplot2 colours are to people with different types of colour vision deficiency (and for different numbers of colours used). 🎨

#RStats #DataViz
A 5x5 grid of maps of France. Each row contains areas shaded with a different number of colours, and each column shows how it looks with different types of colour vision deficiency. None are accessible, except when using only two colours.
