beautiful handmade bump chart, early 1940s
V Robinson The Lent Bumps 1931 - 1940 Pen, ink and watercolour 60 x 48 cm A hand-painted chart illustrating the results of the Lent Bumps from 1931 to 1939, with a note that in 1940 there were 'No Lent Races due to War'. The Lent Bumps, also known as "Lents" or the Lent Races are a set of University of Cambridge rowing races held each year on the River Cam. The races are open to all college boat clubs from the University of Cambridge, the University Medical and Veterinary Schools and Anglia Ruskin Boat Club. The Lent Bumps take place over five days (Tuesday to Saturday) at the end of February / start of March and are run as bumps races (of rowing race in which a number of boats chase each other in single file, each crew attempting to catch and 'bump' the boat in front without being caught by the boat behind). The men's races officially began in 1887 and the women's in 1976. https://www.1stdibs.com/art/drawings-watercolor-paintings/v-robinson-cambridge-rowing-lent-bumps-1930s-chart-pen

I went looking for one Japanese chart book and ended up with 19 prewar volumes, a new collecting method, and a stronger conviction that graphic history is far from fully known.

The right size and color and composition. Culture-specific design uniqueness, often wonderfully weird.

Someone gave me $1,000 to build them a data-graphics library and they now have the second-best collection in San Francisco.

My 2025 New York show did not feel special to me as much as it felt natural. The best way to consume data might not be alone on a pocket screen—but together, in conversation, with human-sized artifacts.

Everything I've learned about charts with two scales (they're not all dueling!): dbtcharts.com/blog/dual-axes…

Every second axis has an exchange rate.

The defensive distrust we developed toward unknown callers and unsolicited emails has now seeped to images and videos. What content is still trustworthy on the Internet? Shared docs and virtual meetings?

Cartographers don’t say geo-visualization or geo-graphic. They say MAP. I don’t know why we bother with "data visualization" when we can just say CHART.

Don't say "data visualizations"

Imprecise and knotty language is bad for charts.
