The players or participants in the transactions are put in a circle. Each one is assigned a sector of the circle based on its “importance”, which is assigned “a priori”. The radius (or height) of the sector shows us the balance or accumulated “value” of every player. All of them start with a zero balance which evolves in time as we move the time window.

Transactions are drawn as curves from one player in the circle to another. The thickness of the curve is related to the amount of the transaction. Bigger transactions get thicker curves. We use the colors to show the direction of the movement (from orange to blue), which is coherent with the color code we use for the players in the circle. Only those transactions that fall within the time window are shown as curves in the circle.

This kind of representation can be useful to explore market transactions (share movements), money exchange between poker players, import and export among countries or any other interaction. This is just a generic demo.

With this visualizer we inaugurate our python framework which is being released under GPL. It intensively uses numpy and OpenGL. This framework is still far from “ready”, but we are working on it and its documentation to get some criticism and maybe participation from others. You can get the code and instructions from the project hosted at google code here or directly download precompiled binaries from this link But we still recommend to read the document. If you don’t have the time to try this, just watch the video above.

You can follow the new products, the development of some experiments and more in the Scopia’s blog. Data.scopia, Plan9, the Fricker’s return, and the graphic products of our 3D department.

We wait you there!

Remember to go down the tree with the arrows or by clicking on the boxes.

Unfortunately, digg rss feed only gives the subcategory for each item. In order to classify them, using the main categories, we have made an external spreadsheet with a list of the items, and we have added the relationships with the different subcategories.

You can have a look at the spreadsheet clicking here, then you will be able to verify that it can also be used to assign colors to the different boxes. To execute the Macro we just do a “join” operation with the rss feed to expand the information for each item.

Enjoy it!

The purpose of this new Macro view is to show a few connected elements at the beggining, and then let you navigate by clicking on the nodes you are interested in. Full information about the elements can be seen just by clicking on the label of the nodes.

In order to show you the capabilities of this Macro, we have made a view of the current news posted at http://meneame.net, an important Spanish news site. We get the information from the rss feed and then visualize it, both articles and categories (tags), as nodes. Therefore, the arched lines between them show how they are related with each other.

Click on the image to execute the Macro.

Notice the list at the left top side of the view. Seldom, one of these graphs will be fully connected. Instead you will get a graph with a some few islands of connected nodes. To switch between them, just click on the elements of this list. Of course, we have a Macro behind that you can see clicking here.

The tutorial about this new features is still in progress. Coming soon for you to build your own graphs.

The first row in the list must be the name of the column, likewise this will be the name of the field that you must write in the RSS block setup or configuration panel. You can also add extra properties to each field items by adding another column to the RSS list.
You can edit or execute a sample with 30 feeds.

Simple idea: Twitter es una comunidad de amigos y extraños -según reza la ayuda- que intercambian instantes de su vida. ¿Qué estás haciendo ahora? Pasamos de la reflexión -herramientas blogging- a la instantánea del pensamiento -twitter-. De esta forma, y en la medida que la gente es sincera y añade sus acciones inmediatas, los más curiosos pueden ir trabando amistades, ya no por afinidades o empatías artísticas, culturales o de intereses personales, sino por compartir momentos tan anodinos que pueden durar segundos o minutos

Por supuesto, el incrustable:

El lema, por su simpleza, me gusta. Detrás de ella se esconde el -quizá- éxito popular de la mayoría de servicios englobados bajo el cajón de sastre de la web 2.0. Un éxito incrementado por un uso colectivo y transparente del servicio que, finalmente, se adhiere al imaginario como parte natural de nuestras vidas. La importancia y éxito de la tecnología o, mejor dicho, el servicio de estas tecnologías web partirá de una idea simple, tanto que, finalmente, su uso diario forme parte de la rutina del usuario.
