another look at this generational chart crime
I've been running a new vis course this semester that empowers students to invest in the vis tools, topics, practices that best align with their careers.
Having a set of well-crafted resources like this to pass on is wonderful.

I lost my job, my kids have measles, and masked secret police roam our streets murdering civilians and abducting the witnesses. But at least now we have full sovereignty over a couple of military bases in Greenland.

I love how this graphic is totally unhelpful for determining whether you're going to get 30 inches of snow or half an inch of ice.

NSF is about to dismantle NCAR at Russell Vought's direction to protect the fossil fuel industry. It's hard to communicate just how much NCAR does, so let's take a look: I've never worked at NCAR, and I've worked with NCAR researchers once ever. What scientific discoveries has NCAR made possible? π

Humans are bad at big numbers. Which makes it easier for billionaires (and trillionaires) to get away with hoarding wealth. Because most people just can't comprehend how much money that is.
So, I appreciate this WaPo effort to help people visualize what ridiculous amounts of wealth really mean.

Can someone tell me what is going on with @economist.com's graphic department? This title also has nothing to do with the plotted data.
Are they using charts as clickbait for the article?

Bumping this because many of us can individually contribute clarity even when facing great uncertainty from the systems around us.
Given funding uncertainty, we wrote about why depts & faculty should try to communicate openly with PhD applicants about any changes to their admissions processes, including if it's "nothing has changed".
Let's do what we can (when we can) to prevent cascading anxiety.
