Contemporary climatic analogs for 540 North American urban areas in the late 21st century - Nature Communications

It is challenging to communicate abstract future climate estimates. Here the authors utilized climate-analog mapping and they identified that North American urban areas’ climate by the 2080’s will become similar to the contemporary climate of locatio…

Most Asian restaurants serve Chinese, Japanese or Thai food in the US | Pew Research Center

In the U.S., 12% of all restaurants serve Asian food; that share is slightly higher than the 7% of the U.S. population that is Asian American.

Our paper with Paul Murrell about color palettes in base R is now published in The :rstats: Journal:

Coloring in R's Blind Spot

Screenshot: Coloring in R’s Blind Spot Abstract: Prior to version 4.0.0 R had a poor default color palette (using highly saturated red, green, blue, etc.) and provided very few alternative palettes, most of which also had poor perceptual properties (like the infamous rainbow palette). Starting with version 4.0.0 R gained a new and much improved default palette and, in addition, a selection of more than 100 well-established palettes are now available via the functions palette.colors() and hcl.colors(). The former provides a range of popular qualitative palettes for categorical data while the latter closely approximates many popular sequential and diverging palettes by systematically varying the perceptual hue, chroma, and luminance (HCL) properties in the palette. This paper provides a mix of contributions including an overview of the new color functions and the palettes they provide along with advice about which palettes are appropriate for specific tasks, especially with regard to making them accessible to viewers with color vision deficiencies.
Screenshot Figure 7: New qualitative palettes in base R available from the palette.colors() function. The label above each swatch shows the argument to provide to palette.colors() to produce the set of colors. The palette at top-left is the new default that is also produced by palette(). The "Okabe-Ito" palette is the default that is produced by palette.colors() (with no arguments).
Screenshot Figure 6: Hue, chroma, and luminance paths for the "YlGnBu" (left) and "Viridis" (right) palettes. These plots are created by the colorspace::specplot() function. For "YlGnBu" we can see that hue changes from blue to yellow, luminance increases monotonically, and chroma has a small peak in the blue range and then decreases with luminance. "Viridis", on the other hand, has almost the same trajectory for both hue and luminance, but chroma increases for the light colors.
Screenshot Table 1: An overview of the new palette functionality: For each main type of palette, the Purpose row describes what sort of data the type of palette is appropriate for, the Generate row gives the functions that can be used to generate palettes of that type, the List row names the functions that can be used to list available palettes, and the Robust row identifies two or three good default palettes of that type. Qualitative: Purpose: Categorical data Generate: palette.colors(), hcl.colors() List: palette.pals(), hcl.pals("qualitative") Robust: "Okabe-Ito", "R4" Sequential: Purpose: Ordered or numeric data (high → low) Generate: hcl.colors() List: hcl.pals("sequential") Robust: "Blues 3", "YlGnBu", "Viridis" Diverging: Purpose: Ordered or numeric data with a central value (high ← neutral → low) Generate: hcl.colors() List: hcl.pals("diverging"), hcl.pals("divergingx") Robust: "Purple-Green", "Blue-Red 3"

Stop what you're doing and read this heart-breaking essay about Long Covid written by Giorgia Lupi:
https://www.nytimes.com/interactive/2023/12/14/opinion/my-life-with-long-covid.html

It shows how large the impact of this type of disease can be and what it does to the lives of people who suffer from it.

I think this is the most emotionally touching piece of #dataviz / essay / opinion piece I have ever read.

If nothing else, it should inspire you to be kind & helpful to others, esp. if they suffer from any kind of disease, chronic or not.


Opinion | My Life With Long Covid

Chronic illness has a way of picking apart your mind and breaking your heart.

Topological data analysis reveals a core gene expression backbone that defines form and function across flowering plants

Topological Data Analysis shows how gene expression shapes the form and function of flowering plants, which have adapted to dominate Earth’s varied landscapes over 125 million years.

Believe it or not, these two charts are showing the same data. The grouped bars chart is from a UN climate report, and the interval bars version is from #TheEconomist. Amazing how much easier the latter is to read with just a few different design choices. #dataviz https://www.economist.com/graphic-detail/2023/11/20/the-world-is-still-failing-to-come-close-to-its-climate-goals
