Hey I'm working a list of "Data Viz dos and don't s"

So far I've collected a few points from Edward Tufte:
- Y-Axis should start a 0
- Check the "Lie Factor": size of a graphic effect divided by the size the effect in the data, it should be close to 1
- "Chart chunk" aka. "Data-to-Ink" ratio: don't use any unnecessary elements which distract from the communication of the data

What else to add?

I created some charts, maps & tables that show the numbers in ...more relative terms. I'm curious what you all think:

👉 Charts I should still build?
👉 Charts I should remove because they're irresponsible?
👉 Data sources I should consider?


Hey anyone knows a nice starting point to get my feet wet with observable?

Hey everyone, what are good DataViz (online) ?
Not data science, I found many of them, I'm looking specific for .
Can you share your experience?
Thanks a lot.

Just paid US$55 for another month of vis.social hosting. I'd love more small, ongoing support here:

People talk a lot about limiting global warming to 2 ºC. But what happens if we don't? In this pretty drastic chart, my colleague @gka explains what different stages of the ongoing climate crisis could look like (it's bad) 🔥 blog.datawrapper.de/climate-cr

I built a Datawrapper chart that doesn't look like a Datawrapper chart anymore 🤔

This is also the last Weekly Chart that I wrote...weekly. Starting next week, all of us start charting & writing. I explain the reasons here: blog.datawrapper.de/weekly-cha

I updated the palette helper I made 5 years ago! Lots of new features:
- quick-editing of input colors
- added charts for saturation+hue
- added colorblind check and simulator
- fixed url serialization bug

Happy coloring!


Until the end of August, the @datavisclub@twitter.com will work through "Observe, Collect, Draw!" by @stefpos@twitter.com & @giorgialupi@twitter.com. I wrote about why you should join us here: blog.datawrapper.de/datavis-bo

I thought it's fun to document my process in the following tweets:

Hi, folks. I no longer have the capacity to run vis.social. Thank you for all of your donations over the past year to cover the costs. We're now spending ~$55/mo. on hosting, plus some administrative costs (like the domain name).

Anyone interested in shepherding vis.social?

Shameless selfpromotion coming in 😆 :
I've released the Game Deru, it's an , for two players. It's purely cooperative and designed as a couch co-op experience.
