The TimeRadarTrees [uni-trier.de] data visualization technique can be used to represent weighted dynamic compound digraphs, which express a sequence of directed and weighted graphs where the nodes correspond to leaves in a hierarchy. The TimeRadarTrees approach shows the information hierarchy as a traditional node-link diagram, but in a radial style. Each graph is represented as a slice on the inner circle and corresponding slices on the smaller outer circles, which are called thumbnails.

Google Adds Visualization Graphs to the Search of Public Data -
With Sunlight Labs questioning the value of goverment-backed visualizations and the UK Department of Communities and Local Government surveying existing approaches to visualizing data in the public realm , the attention to how to make public data more accessible is in full swing. The Google blog just announced that they will " add search to public data ", a new and powerful search feature that makes it easy to find and compare public data, in the anticipation " ... that this will pave the way for public data to take a more central role in informed public conversations ". In practice, this means that when searching for public data related topics, search results will include a small preview and a link to an interactive chart that lets users add and remove data for different geographical areas. The data Google is including in this first launch represents just a small fraction of all the interesting public data available on the web.
Goodbye to Verifiable. I mean it this time. Some of you may remember my previous business, Verifiable.com, which was a cloud service that enabled users to upload data and turn it into pictures. Verifiable.com has been running in read-only mode since I pivoted the business in February of 2010 to start SaneBox . My theory was that so long as the data on Verifable was useful and didn’t require support staff, I would leave it . And remarkably the system has run unattended for all this time; answering questions about unemployment, housing, pollution, prices, concrete production, etc…

LastGraph: About Artist Histories
Last.fm lets you see your top artists each week, but doesn't let you get a good overview of your listening history of each artist. Thus, the new LastGraph feature is artist histories. You can view a history graph for each artist you have ever listened to (yes, even if you only ever listened once), as well as download aggregated history data for each artist in a variety of formats. It's a nice way to see where your allegiences have been in the past, or when you discovered a certain artist; this kind of information is often visible on the posters , but not as clearly, and without a scale.
One of the most frequent questions I get is, " What software do you use to visualize data?" A lot of people are excited to play with their data, but don't know how to go about doing it or even start. Here are the tools I use or have used and resources that I own or found helpful for data visualization – starting with organizing the data, to graphs and charts, and lastly, animation and interaction. by sleepy sparrow
