La boite à outils. Tagline Generator - Timeline-based Tag Clouds - Chirag Mehta : chir.ag. Projects > tagline generator - timeline-based tag clouds Tagline Generator by Chirag Mehta is a simple PHP codebase that lets you generate chronological tag clouds from simple text data sources without manually tagging the data entries.
Once you have populated the data source and configured the generator, it makes a list of all the unique words that have been used and counts how many times each word is used. Next it identifies the different variations of words and combines them under the most common variation using the Porter Stemming Algorithm. E.g. "promised", "promises", "promising", and "promise" might be grouped under "promises". A Suite of Open Source Tools for Creating Custom Maps. MapBox is a suite of open source tools for creating custom maps in Amazon’s cloud infrastructure.
MapBox’s TileMill toolkit is a fully configured open source tile rendering engine designed to create maps using any data set, whether your private data or freely available public sources. MapBox.com also makes large public data sets available for easy access and use. Combining TileMill and these data sets together, MapBox provides the framework that we use to make some of the most beautiful custom maps in the world. Requirements: - Demo: License: License Free.
Wordle - Beautiful Word Clouds. 5 of the Best Free and Open Source Data Mining Software. The process of extracting patterns from data is called data mining.
It is recognized as an essential tool by modern business since it is able to convert data into business intelligence thus giving an informational edge. At present, it is widely used in profiling practices, like surveillance, marketing, scientific discovery, and fraud detection. Processing.org. d3.js.
DataWrapper, a project by DataStory. Improvise. Exploratory visualization based on multiple coordinated views is a rapidly growing area of information visualization.
Ideally, users would be able to explore their data by switching freely between building and browsing in a flexible, integrated, interactive graphical environment that requires little or no programming skill to use. However, the possibilities for displaying data across multiple views depends on the flexibility of coordination, the expressiveness of graphical encoding, and the ability of users to comprehend the structure of their visualizations as they work. As a result, exploration has been limited in practice to a small fraction of useful visualizations. Improvise is a fully-implemented Java software architecture and user interface that enables users to build and browse highly-coordinated visualizations interactively.
Extractiv. GraphStream - A Dynamic Graph Library. Colorbrewer: Color Advice for Maps. 22 free tools for data visualization and analysis. You may not think you've got much in common with an investigative journalist or an academic medical researcher.
But if you're trying to extract useful information from an ever-increasing inflow of data, you'll likely find visualization useful -- whether it's to show patterns or trends with graphics instead of mountains of text, or to try to explain complex issues to a nontechnical audience. There are many tools around to help turn data into graphics, but they can carry hefty price tags.

In this section we'll deconstruct an example of a prefuse application: a simple social network visualization.
Our visualization will provide an animated force-directed layout of a social network, with nodes colored according to gender and showing the names of people they represent. All code presented below is assumed to be within the main method of an application class. The full code for this example is available as Example.java. IMPURE. Application. Protovis. Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.
They way we try to reinforce this, is by providing a map in the Integrated Development Environment (IDE). The map is always visible in the bottom-left, just like the GPS navigation device in your car. Treevis.net.
