check out the pencil icon on the bottom-right; on the new observable you get more of a reading-first experience, but you can still "tinker" with the code if you like

In the chart published today by the New York Times (Stocks Tumble as Investors Balk at Tariff Plan), “the orange bars indicate weekly losses from end of previous week”. How to do this with Plot? observablehq.com/@recifs/week...

A chart showing weekly gains and losses as bands of two opposite colors depending on the sign of the difference. A classic line chart is overlaid, broken by week.

@reka.visionscarto.net and I have used the Imago projection, designed by Justin Kunimune, for a map of early human migrations in @soniashah.bsky.social’s book “The Next Great Migration” (2020) www.visionscarto.net/peopling-the...

A map in shades of gray, showing early human migrations from Eastern Africa to South America.

#30DayMapChallenge today is map projections! You could try one of these with #D3.js d3.observablehq.cloud/d3-geo-polyg...

would it help to add axes? the shape is quite off-center

Added axes on the chart, showing where the origin is compared to the apparent center of the shape

I was ★★ by this very simple and yet powerful interaction pattern that the NYT made on their election polls page; I knew I had to reproduce it. Lots of small details to figure out… now it's available as a reusable options transform for Observable Plot. observablehq.com/@observableh...

I started using #D3js because as an aspiring cartographer I wanted to use the Bertin projection, and it didn't exist. I thought it would be a week-end project. Ten years later, still working on it.

Map of the world projected with Bertin 1953.
