EDge21 Chart and image gallery: 30+ free tools for data visualization and analysis November 7, 2013 03:21 PM ET The chart below originally accompanied our story 22 free tools for data visualization and analysis (April 20, 2011). We're updating it as we cover additional tools, including 8 cool tools for data analysis, visualization and presentation (March 27, 2012) and Six useful JavaScript libraries for maps, charts and other data visualizations (March 6, 2013). Click through to those articles for full tool reviews. Features: You can sort the chart by clicking on any column header once to sort in ascending order and a second time to sort by descending (browser JavaScript required). Skill levels are represented as numbers from easiest to most difficult to learn and use: Users who are comfortable with basic spreadsheet tasks Users who are technically proficient enough not to be frightened off by spending a couple of hours learning a new applicationPower usersUsers with coding experience or specialized knowledge in a field like GIS or network analysis.

UNIX History Below, you can see the preview of the Unix History (move on the white zone to get a bigger image): This is a simplified diagram of unix history. There are numerous derivative systems not listed in this chart, maybe 10 times more! In the recent past, many electronic companies had their own unix releases. This diagram is only the tip of an iceberg, with a penguin on it ;-). If you want to print this timeline, you can freely download one of the following PDF files: Warning: it seems that Adobe Reader has some problems reading the large plotter version of the Unix History chart, but happily you can use another PDF viewer for this task. Here is the ChangeLog of this history. Note 1 : an arrow indicates an inheritance like a compatibility, it is not only a matter of source code. Note 2 : this diagram shows complete systems and [micro]kernels like Mach, Linux, the Hurd... Note 3 : I have now a page where I explain how I build this chart.

Mathway | Math Problem Solver Free Data Visualization and Analysis Tools What it does: Google Refine can be described as a spreadsheet on steroids for taking a first look at both text and numerical data. Like Excel, it can import and export data in a number of formats including tab- and comma-separate text files and Excel, XML and JSON files. Refine features several built-in algorithms that find text items that are spelled differently but actually should be grouped together. After importing your data, you simply select edit cells --> cluster and edit and select which algorithm you want to use. There are also numerical options that offer quick and easy overviews of data distributions. Beyond data housekeeping, Google Refine offers some useful analysis tools, such as sorting and filtering. What's cool: Once you get used to which commands do what, this is a powerful tool for data manipulation and analysis that strikes a good balance between functionality and ease of use. Skill level: Advanced beginner. Statistical analysis The R Project for Statistical Computing

GED Viz, A Data Storytelling Tool | eagereyes I had the honor and pleasure to keynote an event in Berlin recently that introduced a new visualization tool to the world, GED Viz. What makes it stand out from other web-based visualization tools is its focus on particular data, and the ability to create not just individual views, but little stories. GED stands for Global Economic Dynamics, which explains where the motivation for the project actually came from: the need to show the underlying data when explaining global relationships based on the movement of goods, money, and people between countries. The visualization is essentially a chord diagram, showing the countries around a circle and connecting them with bands through the center. What interests me about the project more than the basic visualization is the ability to create little slideshows, or stories. When you open that slideshow in edit mode (by clicking in the lower right), you can create new slides and delete or rearrange existing ones.

Crea rápidamente mapas animados con Tripline La posibilidad de crear mapas personalizados hoy día está al alcance de cualquiera, además usarlos para distintas situaciones y poderlos compartir. Confieso que es un tema que siempre me ha atraído especialmente y me encantan todas las herramientas que nos facilitan y que hacen que esto se haga realidad. En esta ocasión, contamos con Tripline que añade animación y música, el ligero toque que le podría faltar para hacer un mapa mas llamativo e impactante. El año pasado pude probarlo realizando este mapa para el proyecto colaborativo Nuestros Pueblos. Es muy sencillo, solo tenemos que introducir en un buscador que lleva incluido, el lugar que deseemos localizar. Nos da la posibilidad de editar cada sitio con un menú que aparece a la derecha del nombre y complementarlo con mas información, notas y hasta subir fotos de nuestro equipo o que tengamos alojadas en servicios como Facebook, Picasa, Flickr o Instagram. Enseguida ya tendremos el mapa listo para visualizar y compartir (SHARE).
