To show events over time, you can use a timeline, which is often marks on a line that runs from less recent to more recent. But you can vary the shape. Sara Di Bartolomeo and her group researched the effectiveness of different layouts:

Considering the findings of our experiment, we formulated some design recommendations for timelines using one of the data set types we took into account. Here is a list of recommendations regarding timeline readability:

1. Use linear vertical timelines for situations which require fast data lookup.
2. Avoid spiral timelines when the task requires fast lookup.
3. If you use a more creative, expressive shape, such as a spiral timeline, also include a tutorial or visual cues to assist the user in learning and understanding.

Also: it “heavily depends on the context.”

The USGS released a unified geologic map of the moon on a 1:5,000,000-scale — and the data to go with it:

This new work represents a seamless, globally consistent, 1:5,000,000-scale geologic map derived from the six digitally renovated geologic maps (see Source Online Linkage below). The goal of this project was to create a digital resource for science research and analysis, future geologic mapping efforts, be it local-, regional-, or global-scale products, and as a resource for the educators and the public interested in lunar geology. Here we present the completed mapping project as unit contacts, geologic unit polygons, linear features, and unit and feature nomenclature annotation.

That paintball aesthetic is quite becoming.

It looks like a tornado. It’s messy. It’s circular. It almost looks intentionally confusing. But how bad is it really?

At greater disparities between low resources and high volumes of sick people, doctors must decide who lives and who dies, which seems a moral burden with a single case, much less anything more. So systems are setup to relieve some of that pressure. For Reuters, Feilding Cage uses clear illustrations to describe possible policies to help healthcare workers decide who receives care first.

Brian Foo is the current Innovator-in-Residence at the Library of Congress. His latest project is Citizen DJ, which lets you explore and remix audio from the Library:

It invites the public to make hip hop music using the Library’s public audio and moving image collections. By embedding these materials in hip hop music, listeners can discover items in the Library’s vast collections that they likely would never have known existed. For technical documentation and code, please see the repo.

Give it a go. Even if you’re not into making music, you can still explore the sounds, listen to them in their full context, and end up reading about some song written in the early 1900s.

I’ll take all the rabbit holes I can get.

It’d be great if we could conjure a vaccine or a “cure” seemingly out of nowhere just like in the movies. Unfortunately, there’s a necessary process involved to make sure that something works and that it is safe to distribute to billions of people. For New York Times Opinion, Stuart A. Thompson shows typical vaccine timelines, which can take decades, against hopeful coronavirus vaccine timelines.

Medical tests do not always provide certain results. Quartz illustrated this with the accuracy of a simulated antibody test that identifies 90% of those infected and 95% of those not infected:

That means that if you took the test and got a positive result, there’s a 45.1% chance it’s correct. If you got a negative result, there’s a 99.6% chance your result is accurate.

Of course, this doesn’t mean don’t take the test. Detecting 90% of infections with false positives is a good thing. However, it does help to understand what the numbers mean before you do anything with them.

FiveThirtyEight compared six Covid-19 models for a sense of where we might be headed. With different assumptions and varying math, the trajectories vary, but they at least provide clues so that policymakers can make educated decisions.

If you’re interested in the data behind these models, check out the COVID-19 Forecast Hub maintained by the Reich Lab at the University of Massachusetts Amherst. They helped with the FiveThirtyEight comparisons and are also the source for the official CDC forecast page.

The timelines keep shifting and people are getting antsy for many valid (and not-so-valid) reasons. When will this end? Will we ever get “normal” again? At this point, simulations are probably the closest we can get to seeing what might happen next. Marcel Salathé and Nicky Case peer into what happens next with these playable simulations.

Where many simulations have felt like distant, abstract ideas, Salathé and Case’s explanations and interactives are rooted in optimism and practical things that we can do now.

Inspired by the genre of YouTube videos where younger people listen to older music, The Pudding is running a project to find the generational music gaps. Enter your age, songs play, and you say if you know the song or not.

The aggregate results are shown as more people listen. For example, the above shows the percentage of people in a given age group who did not recognize the listed songs.

I’m looking forward to what they do with the finished dataset.

Jukebox from OpenAI is a generative model that makes music in the same styles as many artists you’ll probably recognize:

To train this model, we crawled the web to curate a new dataset of 1.2 million songs (600,000 of which are in English), paired with the corresponding lyrics and metadata from LyricWiki. The metadata includes artist, album genre, and year of the songs, along with common moods or playlist keywords associated with each song. We train on 32-bit, 44.1 kHz raw audio, and perform data augmentation by randomly downmixing the right and left channels to produce mono audio.

A lot of the time, generative music sounds artificial and mechanical, but these results are pretty convincing. I mean you can still tell it’s not from the artist, but many of the examples are listenable.

OpenAI also published the code.

Every month, I collect visualization tools and resources that might help you make better charts. Here’s the good stuff for April.

The Vocal Synthesis channel on YouTube trains text-to-speech models using publicly available celebrity voices. Then using this new computer-generated voice, the celebrities “recite” various scripts. For example, the above is Jay-Z rapping the “To be, or not to be” soliloquy from Hamlet, but it’s not him.

Find out more about the voice generation here, which was developed in 2017. Maybe more interesting, Jay-Z recently filed a copyright claim against the videos.

Many brands that were at-risk before the pandemic or ran with low profit margins might not make it through this thing. The Washington Post used a faux mall map to show the levels of risk:

Companies in this faux mall are rated as speculative investments at Moody’s and S&P as of April 13. These stores are already in financial trouble, and may not be able to access government stimulus money. The stores with the worst ratings are closer to the top of the mall. Brands that are part of the same company, like the Gap and Old Navy, are included in the same storefront.

The above is one level out of four, and each rectangle is sized by a company’s revenue.

I’m getting childhood flashbacks passing time inside the circles of clothes.

The New York Times went through the words used during press briefings, pulling out five main categories and highlighting one in particular:

Viewed simply as a pattern of Mr. Trump’s speech, the self-aggrandizement is singular for an American leader. But his approach is even more extraordinary because he is taking credit and demanding affirmation while he asks people to look beyond themselves and bear considerable hardship to help slow the spread of the virus.

Hm.

We cannot know the true number of coronavirus-related deaths. Maybe it’s because of a lack of tests. Maybe cause of death is ambiguous because of pre-existing conditions. So, for a different point of view, you might compare the usual number of deaths against total deaths. The Washington Post and researchers from the Yale School of Public Health looked at the differences.

As you would imagine, what we search for online shifted over the past few months. The unknowns push information gathering. Schema Design, in collaboration with the Google News Initiative and Axios, broke down the main changes in search since January.

Using a beeswarm chart, each circle represents a query and the size of a circle represents the rank in a query. I really wanted to mouse over the circles to see specifics, but maybe that would’ve been too much information in one view.

Hayleigh Moore for the College of Information Studies at the University of Maryland on visualization and the pandemic:

With new updates developing by the hour amidst the evolving COVID-19 pandemic, trying to grapple at the most relevant information can be overwhelming. Data visualization has helped to synthesize this complex phenomena and shape the timeline of the Coronavirus pandemic that has drastically changed how we go about our daily lives. While commonly used to communicate data to the general population, visualization is now having quite a real-world impact in the face of this crisis.

Visualization the field often struggles with real-world examples for how its work plays a role in people’s lives. There should be no questions about that now.
