What it does: Billed as a Photoshop for data, this open-source beta project is designed for visualizing statistical information, including relationships within networks of up to 50,000 nodes and half a million edges (connections or relationships) as well as network analyses of factors such as "betweenness," closeness and clustering coefficient. But if you're seeking software to do such analysis, one of these might meet your needs. Since I've only had a very basic introduction to that discipline, this is one category of tools I did not test hands-on. Investigative journalists have used such tools to, for example, find links between people who are involved in development projects or who are members of various boards of directors.Īn understanding of statistical theories of network node analysis is necessary in order to use this category of software. These tools use a pre-Facebook/Twitter definition of "social network analysis" (SNA), referring to the discipline of finding connections between people based on various data sets.

Runs on: Windows, macOS X and Linux running Java This app runs on the command line, so users should have the ability to find file paths and plug them into a sample command. In early tests, it didn't know the difference between "it" and "IT," and completely missed "AT&T." What's cool: This is a quick and easy way to find frequency of words in text.ĭrawbacks: Because it's trying to ignore words such as "a" and "the," the basic configuration can miss some important terms. But if you're looking for easy desktop software dedicated to the task, IBM's free Word-Cloud desktop application fits the bill. What it does: Several tools mentioned previously can create word clouds, including Many Eyes and the Google Visualization API, as well as the website Wordle (which is a handy tool for making word clouds from websites instead of text files). But some still enjoy these graphics that display each word from a text file once, with the size of the words varying depending on how often each one appears in the source.

You can think of them as the tiramisu of visualizations - long-ago trendy, now overused. A lot of dataviz experts don't think much of word clouds, considering them both unserious and unoriginal.
