SxSW Interactive, Saturday March 10th

Just a quick note to say that on Saturday March 10th I'll be appearing at SxSWi in Austin, Texas as part of a panel convened by Flickr/geoblogger's Rev Dan Catt entitled "Mapping: Where the F#*% Are We Now?". In the fancy SxSW panel picker, Dan's proposal read:

"Last year online mapping was emerging, now it's everywhere; on your mobile, in your camera, on your wearable head-up display, in your location aware clothing, even on paper and in your kids. Which of those did I totally make up? Guess it's time to check in with those people who actually make maps, merge virtual and real worlds at location flux points, and, you know, put maps online."

It sounds great! I'll be wearing both my old, trusty OpenStreetMap hat and my new, fancy Stamen hat, which should make for an interesting balancing act.

Some Attempts at Twitter Visualisation

Twitter is a website that asks only one thing, "what are you doing?" and aggregates your responses intermingled with the responses of your friends over the last 24 hours. If you let it (I don't) it will SMS you every time your friends update, or if you prefer (I do) it will send you an instant message instead. It will also let you update by web, IM or SMS. It's certainly an easy way to SMS a group of people and only pay for one message, but the IM and web integration mean it's more than just group SMS.

So it's not IM, SMS or the web, but it talks to all three. I like it. I want to hate it. I suppose I cheat, because I don't let it SMS me very often. And maybe because most of my contacts are a continent away, so I only get a few messages a day (they're all asleep). But there it is: I'm not stressed out by it, I'm still Getting Things Done (though that system's not for me, yet). Continuous Partial Attention be damned.

Of course, it's fully Web 2.0 buzz-word compliant, so it has an API that you can use to get data in and out. Not a super-useful one for visualisation, but useful enough to get started. Knocking some ideas back and forth at Stamen with Eric yesterday I decided it was worth trying his idea of plotting twitter activity on a circle. I started with a circle representing the previous 24 hours, rather than a 12 hour clock face, for several reasons:

That's it really.

Given 24 hours of statuses I assigned each user a colour and plotted the status at an angle corresponding to how much of the day had elapsed. I joined each message to the previous message from that person, if there was one. Here is how my first pass turned out:

And here's another variation, still with a colour per person but ditching the arcs and instead using concentric rings for status messages. There are small dots again mapped to time of day. Moire be damned.

The top of the circle is midnight (PST), the bottom is noon. The data was sampled at about 4pm. I'm not sure where this circular/spiral visualisation is going, but if I revisit it I will probably unroll them into a rectangle in the hope that there is space to draw and read the messages. After all, the messages are what it's all about.

These were built with Processing, using the now-built-in XML support and the gorgeous PDF library. I haven't posted the applet because it doesn't work online with the Twitter API, sorry.
