I'm wondering which JS library would be best to dynamically visualize survey data from a postgres db. I've been looking at morris.js, google visualizations, rapael.js, and D3. The survey has_many questions which in turn has_many answers whose votes' columns are incremented by one per an SMS vote(using Twilio). So I'm looking for a charts library that could dynamically update each time my controller receives an SMS, be easy to learn, and ideally have a couple tutorials related to what I'm trying to build.
What have you used and prefer? Any recommendations? Thanks!!
2 big players in this!!!raphael.js and d3.js
D3 for obvious reasons:
based on current web standards(html5,javascript)
good documentation
powerful,robust and reusable
jquery style selection
the only place where raphael defeats d3 is fallback,raphael supports older versions of IE where as d3 is based on current web standards(IE>9)

Try Jasper Reports. Open source and easy to use. I have added helping code on my blog at this link. Exporters for word, pdf, excel and html are mentioned there.

Could anyone please point me to any standard library/ tool that can be used to build a heroku status type dashboard quickly ?
There are several solutions
timeline.knightlab.com is a good fit, you can link a Google Spreadsheet to it and when you add data to the spreadsheet, it will render these data as a timeline on your webpage.
tympanus.net/codrops/2013/05/02/vertical-timeline you can follow this tutorial also, it guides you how to create one, and they have a demo and source code of the demo.
tympanus.net/codrops/2011/12/05/lateral-on-scroll-sliding-with-jquery
is same as above.
Try http://timeglider.com/widget also.
UPDATE
if you want a timeline with 2 axes, you can follow the Tympanus vertical timeline tutorial. Simply creating 2 timelines stacked side by side would do.
Also, you can use two sides of the axis to separate the Dev and Production like in 'lateral on scroll sliding with jquery' example.
If you follow the above tutorials, you can hack the codes to fix it for your need.

I am a bit new to client-side coding, and am looking for a good plugin/tutorial/demo/example to build UIs with ExtJS-MVC.
Please don't start a debate on other frameworks(jQuery/ext etc.).
Thanks.
Sencha is used by over two million developers and its great if you use extjs for building RIAs. Please have a look on resources i provided:
1.Extjs examples has plenty amount of example components which some of them are written in MVC and you may follow their examples.
2.Follow sencha blog and follow their posts regarding extjs.
3.Read Api documentation and follow some of MVC tutorials available.
4.Check sencha learning center's articles and screencasts
5.Subscribe to devzone articles rss feed regarding extjs.
6.Extjs 4 in action will be out sooner or later and you could buy this book while there are plenty of books available for extjs 3.xx and most of content can be applied to extjs 4 with little modification.
7.Tomatocart, Tomatocms,qwikioffice and tine20 are built using extjs 3.xx and you may check their demo section and download their full package and start learning from them.
There are plenty powerful extjs coders here in stackoverflow and you may ask questions if they arent already answered.

Does any one know of any good javascript 3d graphing utility? I know that every site ever recommends Canvas 3d Graph but it is actually quite limiting. For one it only allows graphing with datasets that are within the 1000. Though it does have some capability (with a bit of code modifying) to graph data that are a bit out of its range, nothing out of a complete revamp will allow graphing of data based on time or with values hugely larger than 1000. (I have data values that range into the billions.)
Or should I abandon all hope and either write one myself or look to other technology?
Google O3D is a library for producing 3d-graphics using Javascript. It also has a deprecated plugin, but the newest version uses WebGL.
Check it out here: http://code.google.com/p/o3d/
You'll definitely need to build a small graphing-shell around it, but it shouldn't be hard, especially not if you look closely to the examples provided on the Google-code website.
It uses OpenGL as a backend-technology: rendering lots of polygons, on reasonable hardware, is not a problem at all.

Are there any resources comparing the adoption rates of the various javascript frameworks similar to tcpi? Basically the number of sites using a particular framework on a time-line would be ideal.
I don't know of anything specifically like that, though Google Trends is probably a pretty good indication of popularity. For example, you can compare jquery and mootools:
http://www.google.com/trends?q=jquery,+mootools
You can use google trends for that:
http://www.google.com/trends?q=javascript+jquery%2C+javascript+prototype%2C+mootools%2C+javascript+yui&ctab=0&geo=all&date=all&sort=0
It's not totally accurate since it relies on searches made on google, but it gives a good idea
