🚨 66% of R and Python users do NOT use a formatter 😳 A formatter takes messy code and automatically improves its layout: ✅ Better indentation ✅ Proper spacing ✅ Reasonable line length Poll and explanation in my latest post: 👉 blog.yan-holtz.com

"Python creates only ugly charts" ❌ I wonder how many times I've heard this wrong statement! Matplotlib is very powerful! It's not the most intuitive API, but look what Roy built after investing a few hours in matplotlib-journey.com! Code: github.com/debatreyo/mini_da…

Chord diagrams are a great way to represent flows. BUT, they become very hard to read when there are too many connections. In this chart, Ansgar Wolsing smartly used small multiples to avoid this trap Love it! ❤️ r-graph-gallery.com/best-r-c…
