easy, programmable data plotting

Hi all, I spend most of my time plotting data, but unfortunately I haven't found a decent solution for my plotting needs.

Recommended Data Visualisation Books?

I'm trying to decide on a good set of 4 books that would be considered the "best" books to read for people wanting to learn about how best to display and visualize data. I'm particularly interested in language-agnostic books (e.g. I'm not so interested in books specifically about Processing). Currently I have: Data Visualization - Prin...

Hi R-ers, Does anyone have any good thoughts on how to code complex tabulations in R? I am afraid I might be a little vague on this, but I want to set up a script to create a bunch of tables of a complexity analogous to the stat abstract of the united states, (e.g.: http://www.census.gov/compendia/statab/tables/09s0015.pdf). And I wou...

Tool for displaying binary decision tree

The system I'm currently working on involves the creation of binary decision trees. Lots of them. Some of them are stored in XML format so they can be analyzed manually if needed. The tree structure is basically nested <NODE> tags. Each node may also have a few child tags defining the properties of the node. What I would like to do is ...

matplotlib for R user?

Hi, I regularly make figures (the exploratory data analysis type) in R. I also program in Python and was wondering if there are features or concepts in matplotlib that would be worth learning. For instance, I am quite happy with R - but its image() function will produce large files with pixelated output, whereas Matlab's equivalent figur...

Java - Zoom / 3D Data Visualization Libraries

What are the best libraries/frameworks for doing 3D and/or Zoom interfaces in Java? I'd like to be able to do some prototyping of creating new types of interfaces for navigating within data and representing object graphs/relationships. Low and no cost options are better. Open Source is also a plus. UPDATE: The higher level the api the ...
