22 free tools for data visualization and analysis. Page 10 of 10 Text/word clouds Some data visualization geeks think word clouds are either not very serious or not very original.
You can think of them as the tiramisu of visualizations -- once trendy, now overused. But I 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. IBM Word-Cloud Generator 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). What's cool: This is a quick, fun and easy way to find frequency of words in text. Drawbacks: Because it's trying to ignore words such as "a" and "the," the basic configuration can miss some important terms. Skill level: Advanced beginner. Runs on: Windows, Mac OS X and Linux running Java.

The 36 best tools for data visualization. It's often said that data is the new world currency, and the web is the exchange bureau through which it's traded.
As consumers, we're positively swimming in data; it's everywhere from labels on food packaging design to World Health Organisation reports. As a result, for the designer it's becoming increasingly difficult to present data in a way that stands out from the mass of competing data streams. One of the best ways to get your message across is to use a visualization to quickly draw attention to the key messages, and by presenting data visually it's also possible to uncover surprising patterns and observations that wouldn't be apparent from looking at stats alone. And nowadays, there's plenty of free graphic design software to help you do just that. As author, data journalist and information designer David McCandless said in his TED talk: "By visualizing information, we turn it into a landscape that you can explore with your eyes, a sort of information map. 01. 02. 03. 04. 05. 06.
