What I want is lots of nodes which can expand making a mind map.
I'd ideally like to expand and collapse nodes. I would like to be able to navigate by either dragging around the page, or by following expanded nodes.

I have a colleague who needed that kind of functionalities to graph Maven dependencies between projects. He ended up using FreeMind to do the visualization. He just had to write an XML file conforming to the FreeMind format. I even think you can just use OPML as the file format and find a ready to use XSLT to transform it to the FreeMind format. Maybe FreeMind actually supports OPML directly (I havent used it for a long time).
Once you have your data in FreeMind, you can either export them, or use the FreeMind applet to display an interactive MindMap on your website.

Suggest mxGraph.

Suggest protovis, lovely javascript cross-platform visualisation library.

I think you are asking for a component that does what Visio can do, except that it can be displayed on a web page. Most likely you would have to create one from scratch, because mind mapping tools are always released as products per se and not customizable components. I suggest looking for a basic drawing/illustration component, and then putting your mind-mapping logic in it.

i am working in site that generate Code (chart builder) For Charts.
it's now working with library (chartnew.js). but i want to extend with new chart library.
I used a couple of Javascript charts libraries over the years.
RaphaelJS is my best pick.
However, take a look to the following list provided from that question:
JavaScript Chart Library
RaphaelJS
FlotChart
ExtJS
zingchart
Protovis
D3 JS
Rickshaw
JQPlot
TechOctave charts
RGraph
DojoToolkit
In the future, you may want to post questions like this in softwarerecs.stackexchange.com. This question will likely be closed as it violates the policies of this particular site.
However, I'll answer your question here just in case. There are quite a few JavaScript charting libraries out there for you to use in your web app, all with various pricing structures - Highcharts, Fusioncharts, amCharts, and the one that I'm suggesting - ZingChart. ZingChart can be licensed, but the entire library can be used in your web app for free with a small logo in the bottom right corner. It's incredibly easy to implement and has every chart type and feature you need.
You can view live demos on our Kitchen Sink to get a feel for the library. I'm on the ZingChart team and we're available for any questions you might have at support#zingchart.com!
You could use flotcharts. This is a jquery pluggin

I'm looking for a very simple wordpress plugin and after looking through a couple thousand plugins on the wordpress site, I thought maybe someone here can point me in the right direction.
I need to have a small admin section to save simple key value pairs (strings, or ints), and have the ability to pull those values out with a snippet of code in the template.
This data needs to be available site wide (not custom fields within a post).
It's for a non-profit with no budget, so I'm hoping to not have to write something. They just need the ability to go into the back end, and update a few fields (number of donations, total value of donations, and the location of the next school they will be visiting), and those values will be outputted into the header and inside the body of a few pages.
Any ideas?
Thanks very much in advance,
B
For anyone wondering: I found this: http://wordpress.org/plugins/simple-custom-website-data/
It works exactly as I needed.
Thanks
Assuming this is just for a select set of options and adding options does not need to be dynamic... You should just create a plugin.
Its very basic stuff, options and setting a admin page.
It doesn't get any easier than that for creating a plugin.
You could probably just Google Creating you first WordPress plugin and any of the tutorials will almost give you the exact code you need.

I'm working on an opensource project on Github. I'd created some documents in Github's md format. However I want those documents available in three formats:
PDF: To be downloaded with project
HTML: To be hosted on my personal site.
Markdown (.md): For Github.
Obviously I'd not prefer to write them thrice. Is there any way I write it once anywhere (although MS Word preferred) and it could be converted to other two formats?
Consider Pandoc
I'd write in Markdown and convert to the others.
Another possibility is DITA. Its free reference implementation, the DITA Open Toolkit, lets you generate HTML and PDF out of the box, and can be customized to generate Markdown as well.
But, DITA might be a more sophisticated solution than you need, depending on your requirements for content reuse, the size of your docs, how frequently you update, whether you will be employing a technical writer to maintain and update your docs... It's a powerful solution better suited for a dedicated documentation effort than a one time ad-hoc situation.

Is there any good Scala or Java library for image manipulation? For simple tasks like composing an image with some others then generating a thumb?
Take a look at https://github.com/sksamuel/scrimage (Disclaimer: I am the author)
This is an open source Scala image library that essentially wraps java.awt Image operations in a nicer API.
You asked how to generate a thumbnail, you would do something like.
val in = ...// some input stream
val out = ... // some output stream
Image(in).scale(300,400).write(out, Png)
You can change the scaling method (Bicubic by default) and the output format.
they're all a bit old school, and maybe inconvenient, but java.awt, java.awt.image, and javax.imageio has everything you need to blend and rescale images. You can find some blending example code e.g. here
http://www.curious-creature.org/2006/09/20/new-blendings-modes-for-java2d/
you can find some examples of rescaling and generating image bytes e.g. here
https://sourceforge.net/projects/ssim/?source=directory
there are probably newer/easier solutions, but these do work.
It's not Scala-specific, but ImgLib2 is a full-powered Java image processing library. It's geared towards scientific/low level use, so it might not be as easy as you want for what you're looking for, but it can almost certainly manage anything you're likely to want.
There are also a lot of nice image filters in this Open Source library:
http://www.jhlabs.com/ip/filters/
Since the question is tag with java-2d you know you can use any Java library. A quick google revealed this SO answer:
open source image processing lib in java

Anyone know of a system or framework for a non-programmer form creation? Not a full implementation, but something that handles the designer aspect and something that handles the displaying for being filled in. All the logic we'll be doing. Maybe just a pair of widgets.
We've got a client-server application into which normal users enter and modify data in a thick client and we want to allow the customers to update and create forms with another thick client application, rather than calling us every time they need a letter changed. We want something to do the display bits while we implement the various hooks and functions the system uses.
We're a java shop, but we expect that we're open to writing these clients in another language if it'll be easier.
Possibly Xopus with a schema for the XForm could work.
http://xopus.com/
Try searching for XForms libraries and tools. XForms is a new-ish standard format for defining forms and there are some libraries and tools available for it. Haven't tried any of these myself.
EDIT:
This looks interesting: http://www.orbeon.com/forms/builder
Well, you're a Java shop so this might not be the best tool for you, but from you description you look like a classic case for Infopath:
