@nrennie Great visualisation! Thank you, I like to show my students why I'm insisting on scales like the #viridis scales.

(for those wondering, the dichromat package does a great job at simulating different types of colorblindness)

Dear #RStats , I tend to use #ggplot2 for my plots and the #viridis color palette. However, if I need to print a poster, the printing services always change the palette to a #cmyk palette. Is there any way to use in #ggplot2 a #cmyk palette resembling #viridis ? Thanks!

I'm "strangely attracted" to these. Figures and video show (René) Thomas' attractor. For these visualizations, I set b=0.19 and initialized the orbits at z=1.

I guess one reason why I haven’t done heat maps before is because I don’t think they are as useful compared to other cartographic #dataviz techniques such as binning and choropleths. But maybe I’m missing something?

Anyway, for the heat map, I used the Leaflet.heat #LeafletJS plugin by Volodymyr Agafonkin, creator of Leaflet: https://github.com/Leaflet/Leaflet.heat

The hexbin map uses the #H3 hex grid system with the #Viridis Inferno sequential palette.

#30DayMapChallenge 🗺️ Day 8️⃣: #HumanitarianDataExchange (#HDX)

I have questions. 🙋

I was browsing the HDX data on #ClimateChange and found this wind speed hazard data from #ETHZürich Weather and Climate Risks group generated using their Climada tool. What’s interesting was they provided wind speeds in a ~4×4–km grid but as a CSV file! I had no idea what the data looked like and so I rendered it as a map with the speed colored using the #Viridis Mako palette (originally from seaborne).

#30DayMapChallenge 🗺️ Day 4️⃣: Hexagons

Because the prompt says to use a hex grid, I couldn’t do what I did last year: https://en.osm.town/@seav/111380068524261286

So I took this opportunity to play around with Uber’s H3 grid system: https://h3geo.org/

Anyway, here are three maps showing the #Wikidata items with P625 (coordinates) where P17=Q928 (country = #Philippines 🇵🇭) aggregated (binned) into H3 hexagonal cells in three different resolutions (4 to 6) and colored with the #Viridis Inferno palette.

I had so much fun creating a #polygon map for the third day of the #30DayMapChallenge!

After learning about the #Voronoi algorithm through this toot (https://mapstodon.space/@geum/111347810658578083), I learned how to create them in #QGIS and applied my learnings to the 10 provinces in #Belgium. I applied the #Viridis color palette to make the map readable for the #colorblind.

Belgians may notice the language border and exclaves Komen (Comines) and Voeren (Fourons) are gone. White cell = Brussels-Capital region.

The human eye can see more shades of green than any color. No better time to appreciate that phenomenon than after a spring rain. Beautiful saturated greens everywhere! #Color #Colour #Green #Spring #BayArea #Oakland #Viridis
