The Beauty of Mathematics

I love mathematics (don’t ask, I generally keep that quiet)
I love visualisation, and I love this video!
Don’t worry you don’t have to like or know anything about maths to love this
(you need to watch it full screen to appreciate it)

“Mathematics. Rightly viewed, possesses not only truth but beauty. A beauty cold and austere, without the gorgeous trappings of painting or music”
Bertrand Russel

Information Visualization Definition

Data: a record of related quantities
Information: organised data
Information Visualisation: schematically represented information

But that only defines what it is, not it’s purpose & why?
Purpose: “to clearly communicate information, stimulating viewer engagement & attention”
Why?: To gain knowledge (meaningfully interpreted information)

There’s a balancing act a creative must perform between form & function, plus they’re influenced heavily by the audience. An infographic is often designed to provoke discussion or promote an idea, so can afford to be more visually rich than a visualisation that’s main objection is analysis.

Personally I define the differences between Infographics and Information Visualisation as:
Infographics: present the viewer with a conclusion or a story
Information Visualisations: give the viewer a means to discover their own conclusions

WiFi Visualisation as You’ve Never Seen it Before

“In order to study the spatial and material qualities of wireless networks, we built a WiFi measuring rod that visualises WiFi signal strength as a bar of lights. When moved through space the rod displays changes in the WiFi signal. Long-exposure photographs of the moving rod reveal cross sections of a network’s signal strength.”

The Doctor Will Actually See You Now

A common problem faced by patients, is keeping track of their condition and remembering dates and details when asked for information by a physician. I’d pondered creating a personal visual health diary app in the past, something that prompts a patient to input information about their condition, be it hourly, daily, weekly etc. This data could then be presented to the physician in a visual and interactive way.

And I’m not the only one to think this could be useful, Katie McCruddy, a Myasthenia Gravis sufferer, has kept a detailed diary of her condition from the age of 13, but she is also an interactive designer, so when she was faced with explaining her condition and history to a new physician she thought visualisations would help get the details across quickly and effectively.

To see how effective it was see these posts The Timeline & The Consultation

Pulse of the Nation

I love data visualisation, in fact I was given a wonderful book entitled “Information is Beautiful” by David McCandleless as a present a few days ago… anyway I just stumbled across this on Mashable

The video shows the mood in the U.S., as inferred using over 300 million tweets, over the course of the day. The maps are represented using density-preserving cartograms more info here
