Bird songs stunningly visualised in animation
As part of the Europeana Creative project, Sound and Vision commissioned Australian artist Andy Thomas to create an inspirational digital sound sculpture re-using two bird sounds from its archive. The result is a visually mesmerizing artwork that has been very well received. If you would like to know more about how this video was made

Data visualization: ambiguity as a fellow traveler : Nature Methods : Nature Publishing Group
Being sure is good; being uncertain is not necessarily bad. Research teams are working to render uncertainty visual.
via Data visualization: ambiguity as a fellow traveler : Nature Methods : Nature Publishing Group.
The visualization platform Caleydo has a functionality called StratomeX that reveals uncertainty factors in data analysis. Shown here, different clustering algorithms used to slice through the same brain-tumor gene expression data lead to different results. Algorithms: non-negative matrix factorization method (left), consensus hierarchical clustering method (center) and consensus hierarchical clustering method after manual curation of the data (right).
This paper looks at the uncertainty in statistical analysis and how differing results and data uncertainties can affect how we ‘read’ data.
To do: check out consensus clustering etc.

A Taxonomy of Data Visualization
For some time at Visualizing, we’ve been working on a commonsense taxonomy of data visualization. This is still a work in progress, but we wanted to involve the wider community in the discussion.
There are already all-inclusive glossaries of specific techniques, and there are several academic approaches to classification (Bertin, Schneiderman, etc.). But we’re looking for something in between: a general, top-level language to describe the forms used in visualization and information graphics. It should be useful to experts and non-experts alike, and so requires a balance between familiar words and ideas on the one hand and rigorous thinking on the other.
