#TodayinHistory #dataviz #Onthisday #OTD 📊 🎂May 23, 1667 Jacob Cristoph Le Blon born in Frankfurt am Main, Germany 🇩🇪 In 1710 he invented three color printing using an RYB or RYG color model which later morphed into the modern CMYK system, better for printing.

Portrait of Christof Le Blon, illustrating how a color photo can be composed by overlaying green, yellow and red images.

In 1721 Le Blon issued a separate print depicting the male sexual organs entitled Préparation anatomique des parties de l’homme, servants a la generation, faites sur les decouvertes les plus modernes.

#TodayinHistory #dataviz #Onthisday #OTD 📊 🎂Apr 19, 1801 Gustav Theodor Fechner born in Groß Särchen, Germany 🇩🇪 Oct 22, 1850: Fechner's Law: the subjective sensation is proportional to the log of stimulus intensity -- used as an early idea for accuracy of graphic elements -- length, angle, area,..

Graphic illustration of Fechner's Law. It plots intensity, I, of a stimulus on the horizontal axis vs. the strength S of the sensation on the vertical. The curve shows Fechner's Law, S = k log I

I updated this chart, which I made a few years ago. I like the clustering and how the tails help tell a story. This is a particularly useful application of connected scatterplots. Not sure if two juxtaposed line charts would communicate better. #30dayChartChallenge.

A connected scatetterplot comparing education with GDP per capita in purchasing power parity (PPPs) from 2005 to 2023 for various European countries. The main title reads “Education vs. GDP per Capita PPPs (2005-2023)” and the subtitle explains that Portugal’s sharp recent growth in the percentage of people aged 25 to 64 with secondary or higher education has been accompanied by an increase in GDP per capita only in recent years, while former communist countries display oblique line trends that indicate growth in both dimensions. The horizontal axis represents GDP per capita (ranging from 0 to 250), and the vertical axis shows education percentages (from 25 to 100%). Countries are grouped by region—Western Europe and Eastern Europe—each distinguished by different colors. Data points for 2023 are highlighted with circular markers and country labels.

A Venn diagram titled 'The Four Elements That Make An Impactful Infographic' showing the intersection of four main elements: 'data information' (yellow), 'concept, question' (blue), 'goal, function' (pink), and 'visualisation design' (grey). The overlapping sections contain specific elements like 'wireframe', 'plot', 'template', and 'rough sketch'. The central overlap shows 'impact', while some intersections are labeled as 'BORING' or 'USELESS'. Created by Information is Beautiful for their training intensives

Our recently published paper focuses on the stratigraphic structure and chemical composition of historical photographic negatives. We used linear and nonlinear techniques to investigate the gelatin-base emulsion layers over glass supports. Have a look here 👇🏾

Thread - I've been thinking a lot about Walter Lippmann’s Public Opinion lately, especially in the context of Musk’s role in dismantling the federal workforce through DOGE. It’s a perfect example of what Lippmann warned about over a century ago.

A data descriptor in Scientific Data presents Style Aligned Artwork Datasets (SALAD), and an example of fruit-SALAD with 10,000 images of fruit depictions, which provides a benchmark dataset for computer vision. go.nature.com/4ba23L0 🧪

This is figure 1, which gives an overview of the first instance of 10 fruit categories in 10 styles. Columns display fruit categories and rows display style categories with labels trying to describe the style prompts. The full dataset contains 100 instances of each category-style combination resulting in 10,000 unique fruit depictions

I'm agonizing over an essay I'm writing about storyFINDING vs. StoryTELLING vs StorySPINNING. I'm in the "it's easier to research than to write" phase. I came across this terrific post (and viewpoint) from @visualisingdata.com. See visualisingdata.com/2015/02/visu...

Very interesting paper: "A Grammar of Hypotheses for Visualization, Data, and Analysis", by Remco Chang's group arxiv.org/abs/2204.14267 This will definitely go into my #dataviz course, and can anchor several of the discussions we have with collaborators.

The relationships between three hypothesis spaces, formalized using the author's proposed hypothesis grammar.
