Astronomical Typography

Typography meets astronomy in 16th century books like the Astronomicum Caesareum.

It is arguably the most typographically impressive scientific manual of the sixteenth century. Owen Gingerich claimed it, “the most spectacular contribution of the book-maker’s art to sixteenth-century science.”

A blog dedicated to data visualisation, all part of ongoing research for a book on Charles-Joseph Minard.

Data visualisation, interactive media and computational design are one focus of my work, but I also do research in the history of maps and diagrams.

Shipmap.org | Visualisation of Global Cargo Ships | By Kiln and UCL

A beautiful visualisation of shipping routes and cargo. Mesmerising!

You can see movements of the global merchant fleet over the course of 2012, overlaid on a bathymetric map. You can also see a few statistics such as a counter for emitted CO2 (in thousand tonnes) and maximum freight carried by represented vessels (varying units).

Sessions Map

This is nifty—a map of all the Irish music sessions and events happening around the world, using the data from TheSession.org.

If you’re interested in using data from The Session, there’s a read-only API and regularly-updated data dumps.

Animated SVG Radial Progress Bars - daverupert.com

Using a single path SVG, a smidge of CSS, and ~6 lines of JavaScript.

In this days of monolithic frameworks, I really like seeing modest but powerful patterns like this—small pieces that we can loosely join.

Cognitive Overload - daverupert.com

From Scott McCloud to responsive design, Dave is pondering our assumptions about screen real estate:

As the amount of information increases, removing details reduces information density and thereby increasing comprehension.

It reminds me of Edward Tufte’s data-ink ratio.

Web Typography: Designing Tables to be Read, Not Looked At · An A List Apart Article

An extract from Richard’s excellent book, this is a deep dive into styling tables for the web (featuring some CSS I had never even heard of).

Tables can be beautiful but they are not works of art. Instead of painting and decorating them, design tables for your reader.

(It also contains a splendid use of the term “crawl bar.”)

Sonic sparklines

I’ve seen some lovely examples of the Web Audio API recently.

At the Material conference, Halldór Eldjárn demoed his Poco Apollo project. It generates music on the fly in the browser to match a random image from NASA’s Apollo archive on Flickr. Brian Eno, eat your heart out!

At Codebar Brighton a little while back, local developer Luke Twyman demoed some of his audio-visual work, including the gorgeous Solarbeat—an audio orrery.

The latest issue of the Clearleft newsletter has some links on sound design in interfaces:

I saw Ruth give a fantastic talk on the Web Audio API at CSS Day this year. It had just the right mixture of code and inspiration. I decided there and then that I’d have to find some opportunity to play around with web audio.

As ever, my own website is the perfect playground. I added an audio Easter egg to adactio.com a while back, and so far, no one has noticed. That’s good. It’s a very, very silly use of sound.

In her talk, Ruth emphasised that the Web Audio API is basically just about dealing with numbers. Lots of the examples of nice usage are the audio equivalent of data visualisation. Data sonification, if you will.

I’ve got little bits of dataviz on my website: sparklines. Each one is a self-contained SVG file. I added a script element to the SVG with a little bit of JavaScript that converts numbers into sound (I kind of wish that the script were scoped to the containing SVG but that’s not the way JavaScript in SVG works—it’s no different to putting a script element directly in the body). Clicking on the sparkline triggers the sound-playing function.

It sounds terrible. It’s like a theremin with hiccups.

Still, I kind of like it. I mean, I wish it sounded nicer (and I’m open to suggestions on how to achieve that—feel free to fork the code), but there’s something endearing about hearing a month’s worth of activity turned into a wobbling wave of sound. And it’s kind of fun to hear how a particular tag is used more frequently over time.

Anyway, it’s just a silly little thing, but anywhere you spot a sparkline on my site, you can tap it to hear it translated into sound.

ARP Observatory (@ArpObservatory) | Twitter

In July we started receiving audio signals from outside the solar system, and we’ve been studying them since.

Tweets contain sound samples on Soundcloud, data visualisations, and notes about life at the observatory …all generated by code.

ARP is a fictional radio telescope observatory, it’s a Twitter & SoundCloud bot which procedurally generates audio, data-visualisations, and the tweets (and occasionally long-exposure photography) of an astronomer/research scientist who works at ARP, who is obsessive over the audio messages, and who runs the observatory’s Twitter account.

Month maps

One of the topics I enjoy discussing at Indie Web Camps is how we can use design to display activity over time on personal websites. That’s how I ended up with sparklines on my site—it was the a direct result of a discussion at Indie Web Camp Nuremberg a year ago:

During the discussion at Indie Web Camp, we started looking at how silos design their profile pages to see what we could learn from them. Looking at my Twitter profile, my Instagram profile, my Untappd profile, or just about any other profile, it’s a mixture of bio and stream, with the addition of stats showing activity on the site—signs of life.

Perhaps the most interesting visual example of my activity over time is on my Github profile. Halfway down the page there’s a calendar heatmap that uses colour to indicate the amount of activity. What I find interesting is that it’s using two axes of time over a year: days of the month across the X axis and days of the week down the Y axis.

I wanted to try something similar, but showing activity by time of day down the Y axis. A month of activity feels like the right range to display, so I set about adding a calendar heatmap to monthly archives. I already had the data I needed—timestamps of posts. That’s what I was already using to display sparklines. I wrote some code to loop over those timestamps and organise them by day and by hour. Then I spit out a table with days for the columns and clumps of hours for the rows.

I’m using colour (well, different shades of grey) to indicate the relative amounts of activity, but I decided to use size as well. So it’s also a bubble chart.

It doesn’t work very elegantly on small screens: the table is clipped horizontally and can be swiped left and right. Ideally the visualisation itself would change to accommodate smaller screens.

Still, I kind of like the end result. Here’s last month’s activity on my site. Here’s the same time period ten years ago. I’ve also added month heatmaps to the monthly archives for my journal, links, and notes. They’re kind of like an expanded view of the sparklines that are shown with each month.

From one year ago, here’s the daily distribution of

And then here’s the the daily distribution of everything in that month all together.

I realise that the data being displayed is probably only of interest to me, but then, that’s one of the perks of having your own website—you can do whatever you feel like.

When I was in Düsseldorf for this year’s excellent Beyond Tellerrand conference, I had the pleasure of meeting Nadieh Bremer, data visualisation designer extraordinaire. I asked her a question which is probably the equivalent of asking a chef what their favourite food is: “what’s your favourite piece of data visualisation?”

There are plenty of popular answers to this question—the Minard map, Jon Snow’s cholera map—but we had just been chatting about Nadieh’s previous life in astronomy, so one answer popped immediately to mind: the Hertzsprung-Russell diagram.
