Good Java graph algorithm library?

Has anyone had good experiences with any Java libraries for Graph algorithms. I've tried JGraph and found it ok, and there are a lot of different ones in google. Are there any that people are actually using successfully in production code or would recommend?

Good PHP ORM Library?

Is there a good object-relational-mapping library for PHP?

I know of PDO /ADO, but they seem to only provide abstraction of differences between database vendors not an actual mapping between the domain model and the relational model. I'm looking for a PHP library that functions similarly to the way Hibernate does for Java and .NET.

A better Java JSON library?

Can anyone recommend a good Java JSON library (better than the one from http://json.org/ )? I've also found JSON-lib, which definitely looks like an improvement, but I'm wondering if there is anything that is even better than that?

C++: what regex library should I use?

Open source java library to read ECG data?

Can Someone suggest me a good open source java library to read ECG data in MFER / HL7 / Other formats?

javascript data structures library

I'd like to ask for recommendation of JavaScript library/libraries that supply an implementation of some basic data structures such as a priority queue, map with arbitrary keys, tries, graphs, etc. along with some algorithms that operate on them.

I'm mostly interested in:

• The set of features covered,
  
  



• Flexibility of the solution - this mostly applies to graphs. For example do I have to use a supplied graph implementation,
  
  



• Use of functional features of the language - again it sometimes gives greater flexibility,
  
  



• Performance of the implementation
  
  

EDIT

Ok, I'd like to point out that I'm aware that it's possible to implement using js the following data structures:

• A map, if key values are either strings or numbers,
  
  



• A set, (using a map implementation),
  
  



• A queue, although as was pointed out below, it's inefficient on some browsers,
  
  

At the moment I'm mostly interested in priority queues (not to confuse with regular queues), graph implementations that aren't very intrusive as to the format of the input graph. For example they could use callbacks to traverse the structure of the graph rather than access some concrete properties with fixed names.

Javascript zoom library isn"t working

i am using this library zoomooz.js and i implemented it on my website but it isn't working, i followed the examples which came with the library but it only seems to work on the background. When i click on an article to zoom to i get an error in the google chrome console saying: "Uncaught TypeError: Object # has no method 'initialize'" in the "jquery.zoomooz.js:294" but i dont think it is a good idea to change the library so it must be an other problem sinds it works fine in the examples.
