Software Cartography — “It is our vision that developers can speak of code as ‘up in the north’, ‘over in the west’, or ‘down-under in south’. We want to provide developers, and everyone else involved in software development, with a shared and spatial and stable mental model of their project. 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. For each development task, related information is displayed on the map.” The consistent layout of codemaps helps to establish a stable mental model of software systems. Software Cartography helps to navigate within a software system. relate different metrics to each other, eg search results and bug prediction. stay aware of the actions of other developers of your team, understand a system’s domain upon first contact. explore a system during reverse engineering. On a codemap we can display David Erni.
chron'ooo -Chron’OOo propose dans la Gallery, un thème Chronologie / Outils qui permet de glisser divers objets graphiques, orientés chronologie. - Dans le module Texte, "Writer", il suffira d'utiliser la barre d’outils de dessin, barre très simplifiée de 12 outils fondamentaux qui conviennent parfaitement à toute réalisation de type schéma, en particulier les outils "zone de texte" et "légendes". Elle permet des réalisations variées pour enrichir et compléter les chronologies qu’un néophyte pourra concevoir très rapidement. -Dans le module Dessin vectoriel, "Draw", les outils très variés et puissants permettent de concevoir des axes ou frises chronologiques de grande qualité tant les possibilités sont riches ; à noter que Draw permet de modifier tous les objets et l’existence de "calques" qui autorisent de travailler en couches, ainsi les utilisateurs expérimentés pourront créer des documents de niveau professionnel. La Gallery, en affichant des objets en miniatures, simplifie le travail.
RichAnalysis | vision + solution = intelligence d3.js Croquis de géographie 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. The cost can make sense for professionals whose primary job is to find meaning in mountains of information, but you might not be able to justify such an expense if you or your users only need a graphics application from time to time, or if your budget for new tools is somewhat limited. Here's a rundown of some of the better-known options, many of which were demonstrated at the Computer-Assisted Reporting (CAR) conference last month. Data cleaning DataWrangler What's cool: Text editing is especially easy.

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. There are four kinds of tasks that are normally involve in Data mining: * Classification - the task of generalizing familiar structure to employ to new data* Clustering - the task of finding groups and structures in the data that are in some way or another the same, without using noted structures in the data.* Association rule learning - Looks for relationships between variables.* Regression - Aims to find a function that models the data with the slightest error. For those of you who are looking for some data mining tools, here are five of the best open-source data mining software that you could get for free: Orange RapidMiner Weka JHepWork
ImagePlot visualization software: explore patterns in large image collections What is ImagePlot? ImagePlot is a free software tool that visualizes collections of images and video of any size. It is implemented as a macro which works with the open source image processing program ImageJ. ImagePlot was developed by the Software Studies Initiative with support from the National Endowment for Humanities (NEH), the California Institute for Telecommunications and Information Technology (Calit2), and the Center for Research in Computing and the Arts (CRCA). See your whole image collection in a single visualization. Existing visualization tools show data as points, lines, and bars. Better understand media collections and make new discoveries. Visualize image collections as timelines and scatter plots which display all images in a collection. Visualize change. We include macros which automatically measure various visual properties of every image in collection (or every frame in a video). Visualize image collections of any size. From a few dozens to millions of images.
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. Protovis is free and open-source, provided under the BSD License. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates June 28, 2011 - Protovis is no longer under active development. September 17, 2010 - Release 3.3 is available on GitHub. May 28, 2010 - ZOMG! October 1, 2009 - Release 3.1 is available, including minor bug fixes. September 19, 2009 - Release 3.0 is available, including major performance improvments, bug fixes, and handy utilities such as scales and layouts. Getting Started How does Protovis work?

GGobi data visualization system. 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.
