Data Visualisation

  1. 1. ManyEyes What is it?Web 3 brings together the tools that make technologies work better for the people that usethem. As a tool which puts this into practice, ManyEyes brings together visualization toolsthat make the analysis of information easier to understand and enable staff to make the bestuse of such analysis to inform decisions on how they improve their services. Why are we researching this?ManyEyes can help tackle the information overload – making quantitative (such as statistics)and qualitative information (like policies, evaluations or even online conversations) moremeaningful to those people who haven’t necessarily created the knowledge in the first place.For example, a statistician may have created datasets on a customer group but it’s theservice manager that is best placed to make use of them to personalise the service. A webdeveloper may have set up a tool that enables the public to comment on a particular issue,but it is the policy officer that needs to use that feedback when formulating policies.ManyEyes can also help us open up our expertise from staff to the public – a priority in the“Future Challenges” agenda - so they can make better decisions on areas that affect them.For example, GapMinder and the New York Times Visualization Lab have been veryeffective in enabling people to manipulate information such as longitudinal statistics tomeasure the impact of a policy over time and place, government spending or crime rates.In other words, it can allow policy makers and resource managers to pick up on new trendsand unmet needs by visualising different types of information, while allowing the public tobecome more informed citizens.ManyEyes Wikified can enable staff to collaborate in providing the necessary context tothese visualisations. How can you develop this?

ManyEyes is an online based data visualization tool, using Java applet technology (which can be downloaded here and needs to be Java 1.4 or above). It is recommended to run on either Internet Explorer 6 or Firefox 1.0.6 – naturally it’s preferable if more updated versions are used. IBM has advised that it may not be bug-free as it is still a proof of concept. The colour palettes have been chosen to make sure that people who are colour blind can visualize the data, while the data is set out in a text format that can be used by screenreaders. Similar applications currently used within the Council, such as Xcelsius – used by Personnel Information Systems, Employee Services, KASS Finance and Business Performance Monitoring, require a high level of expertise and experience of both Xcelsius and Excel.
