#dataviz is a long, iterative process.

If you want to learn the required steps to create a great graph with R and ggplot2,

we are building something for you with @CedScherer !

@ArthurGailes Interesting, for me the other one was more logical! It's anyway just a leftover Ive stuck to but it doesn't appear on the page.

@morganthegray @mdancho84 Thanks for tagging me 🙏

@mdancho84 @Farid76808744 Most codes are on my GitHub. The coffee, X-men, and astronaut visualizations are contributions to TidyTuesday, source codes here: https://t.co/YK0XPPyxdn

R blows my mind.

All of these were made with R by Cédric Scherer (3 is my favorite):

@mdancho84 Thanks Matt 👐 For the stream graph in the original tweet ggplot2 was only used from the basic plotting, but all others are (mostly) #rstats only 🖥️

[Joachim Schork @JoachimSchork]

Measuring streamflow droughts can be a statistical challenge! Recently, I stumbled upon an interesting project in this field.

The analysis of "100 Years of Streamflow Droughts," shared in a recent post by @CedScherer, highlights a significant project in collaboration with the U.S. Geological Survey (USGS) Viz Lab. This project examines long-term data on streamflow levels in the US over the past century, revealing key patterns and trends.

This map showcases the 1,000 most severe streamflow droughts from 1920 to 2020, using data from 3,196 gages with reliable and continuous records. This visualization is instrumental in understanding how streamflow droughts have evolved over time.

Additionally, the small multiples graph provides a decade-wise breakdown of streamflow droughts, categorized by climatic hubs and severity. This detailed visualization helps us comprehend the regional impacts and trends in drought severity.

I'm in Washington DC for a few days to host a workshop 🧑‍🏫

If you're around, feel free to reach out—I'd love to connect and hang out!

[Cédric Scherer @CedScherer]

@d_mykhailyshyna @MonikaPompeo @zuchowskidavid @yukitakahashi11 @AnastassiaFedyk @Alessia_metrics @GaborBekes @TaniaBabina @wolfgangkhuber @TDeryugina @MaksymPolyakov Sorry, not that active here anymore. Hope you had a good session nevertheless!

@SteveFranconeri Hi Steve, unfortunately, the link seems to have expired. I'd love to include this resource, preferably in PDF format, during my workshops.

Is there any chance you could upload it again? Or perhaps there's an existing link that I may have overlooked?

[Cédric Scherer @CedScherer]

@oded_tal @AlisonGreggor @SwaddleJohn @alli_sabo @TeamMarmot Yeah, I can totally see the reasoning and it would indeed end up being rather colorful.

[Cédric Scherer @CedScherer]

@BrunoHMioto @TeunvandenBrand @ClausWilke It's similar but not the same. One downside of the treemap is that you loose the visual encoding of the different group ranges. One needs to read the labels carefully.

[Cédric Scherer @CedScherer]

📊 Have you ever needed to create a bar chart when data is aggregated in groups of different ranges? #dataviz

While researching the pros and cons, I couldn't find a consensus on what the "best" approach is. "It depends" is, as often, the best recommendation I could find.

[Cédric Scherer @CedScherer]

@TeunvandenBrand @ClausWilke Yeah, placing the labels inside sohnds like a great idea. I'd never use an y-axis in that case, that would be very confusing and misleading.

[Cédric Scherer @CedScherer]

@GoatShipMate The term histogram is still in use 🤓 But as this has irregular bins, it's not a traditional histogram. And usually those represent frequency by height, or am I wrong? (Well, it's the same if bin width is equal anyway)
