Visualising social networks

Social Networks Visualiser (SocNetV) is a tool for the analysis of Social networks. The networks are portrayed as mathematical graphs or it is possible to load in networks from other sources such as Pajek.  It is also possible to use the web crawler and automatically create networks in a given URL.

The software computes various properties such as density, diameter and distances and structural statistics, such as node and network centralities.

This application was created in a file called Fidg’t. This gives the user the ability to look at the networks tagging habits –i.e. music preferences, photos etc. In Fidg’t there’s a Visualizer and you can use any tag to develop a magnet. This enables people on the network to get drawn towards similar items.

Visualisation tools for Excel data – NodeXL

Microsoft have been developing a system called NodeXL, which stands for:

NodeXL: Network Overview, Discovery and Exploration for Excel
This enables simple visualisations to be made from data in Excel spreadsheets.
The example shown below, NodeXL has imported and displayed a graph of connections among people who follow, reply or mention one another in Twitter.

The second image shows another view of what can be done in NodeXL

NodeXL can import graph data from a variety of file formats, including GraphML, UCINet, Pajek, and matrix. It can also connect directly to the Twitter, Flickr, and YouTube Web sites, letting you import the network of people who have recently tweeted a certain term, for example, or a network of related Flickr tags. NodeXL can import a network from your email (outlook, Windows mail etc) – the network of all the people you communicated with last week, for example. NodeXl also allows Zooming, Panning and Scaling as well as dynamic filtering.

The Billion Pound-o-Gram

UK government spending represented by a billion-pound-o-gram, which gives a broad idea of where the  money comes from and where it goes.

This visualisation created by David McCandless called The Billion Pound-O-Gram mixes up 2008/9 figures from the Treasury and the Guardian. He was especially concerned with the size of the UK budget deficit – the country’s overdraft as he puts it. It’s more than an entire years worth of income tax!

Visualisation of Pride and Prejudice

Phrase net of the words in Austen's Pride and Prejudice

Phrase net of the words in Austen's Pride and Prejudice

This diagram is of a phrase net, which shows the relationships between different words in a text – courtesy of Many Eyes – the IBM visualisation facility.
The phrase net uses a form of pattern matching to give multiple views of the concepts in the book – Jane Austen’s Pride and Prejudice. In this word graph two words are connected when they appear together in a phrase of the form “X and Y”.

Visualisation tool developed for public participation

Visualisation tools for public participation in managing landscape change (VISULANDS)

The Forestry Commission has been active in developing web sites for public participation. In this example they have developed a visualisation for a site in northern Scotland and allowed users to select the type and density of tree planting and see what visual effect that has on the landscape. The Forest Research study site used the visualisation to test different aspects of the project but have now made it available to the public.
