How do I visualise clusters of users?
I have an application in which users interact with each-other. I want to visualize these interactions so that I can determine whether clusters of users exist (within which interactions are more frequent). I've assigned a 2D point to each user (where each coordinate is between 0 and 1). My idea is that two users' points move closer tog...

United States State shapes for Office
I want to create visuals along the lines of CNN's "red-state, blue-state" shadings of the states in the U.S. for my project. I'm planning to do something fancier than just shading the state's shape in a color. Are there open source libraries of state shapes/polygons (or - if not open source - others) that I can import into Word, Excel, e...
Visualization Tools for Huge Graphs
I would like to create a graph (set of vertices connected with edges) and I'm looking for tools or libraries that can help me. The graph is composed of at least 1000 nodes. Although it may be a little ambitious, I'd like to create one that has 60k nodes. Obviously the resulting graph is meant to be artistic more than functional. For ...
Geographical Data Visualization in a Web Application
I've got a request to implement a visualization service for geographical related data. I have a list of Italian ZIP Codes (they are called CAP in Italian).

Visualization data gathering for learning
Hi, I'm just starting to take an interest in visualization and I'd like to know where I can get my hands on some data, preferably real world, to see what queries and graphics I can draw from it. Its more of a personal exercise to create some pretty looking representations of that data. After seeing this I wondered where the data came f...

GraphViz edge labels
Hi... I'm trying to draw a graph of the dependencies between C header files using graphviz. Basically, what I'm doing is log all the #include that appear and the condition (#if conditions I mean). If a file includes another one, it becomes its father in the graph and the potential condition is the edge label. I obtain a pretty large g...
