Telling stories that can only be seen. Data visualisations can be extraordinarily beautiful. Here are but a few tools.
Open-source desktop application, primarily a network visualisation tool, but with plugins galore for space-time extensions.
Beautiful, multivariate statistics. See this phenomenal TED presentation by Hans Rosling – love that guy
Not surprising, Google chart can be a powerful tool. Simple to use and simple to work with fusiontables.
Maybe the most gorgeous multivariable thing around.
It looks a little dated now, but Exhibit, formerly known as Similie, is powerful and do some interesting experiments with time-space.
Another js library, these guys are highly professional. Free versions for non-profits. One really nice thing is that each diagram and graph example on their site links to the respective JSFiddle. Heartwarming.
Very scientific (and therefore console-based), this is made for balancing visual readability with scientific exploration.
Python-based network analysis.
What is says on the box: excel based engine with node-edge emphasis.
Web-based application for exploring graph databases.
Visualising text as a network.
visual document analysis
You would be amazed at how much information can be displayed and explored in Circos.
Here is one pretty specific to analysis of functional genomics. It explores relations in three dimensions: gene activity, pathway data that presents a series of reactions within a cellular process; and phylogenetic data describing ancestral relationships between species. Yay biology!
