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.

I need a javascript grid for representing huge data( i mean thousands of records ) with a pretty fast searching and sorting feature. I've found a few, but i dont really know which would be the best. I would need some basic features built in the grid such as: -sorting, searching in rows, filtering etc.
Anyone know a grid which would suit my needs?
please try using this(JSLightGrid): https://github.com/chanakyachatterjee/JSLightGrid. It's pure javascript(no need of jquery or any other library), responsive and quite fast when comes to huge data. eg sorts 2k records in 52 milliseconds.
Have you tried ag-Grid? It does all the things that you are looking to do. It was written for financial applications, so is very capable with the 'lots of data' requirement.

I'm looking for a useful library which would help me in drawing different interactive charts, graphs etc on canvas. Basically i'm designing a web paint like application and adding the functionality of these interactive charts etc. so what i want is, when user clicks the specific chart, he can then click anywhere inside the canvas and the chart appears there with the data given by user in a file(i will handle that once i know the data format and stuff). I tried a few libraries but either they don't support drawing inside canvas or they aren't offering any interactivity... what do you guys suggest me to go for?
As #Pereira said both chartjs and google chart are good solutions. I will also recommend you take a look at:
HighchartsJS (http://www.highcharts.com/)
PolychartJS (http://www.polychartjs.com/)
I hope it helps you.
Here we have someones:
http://www.chartjs.org/
https://developers.google.com/chart/
I think both are good solutions to you.
I just finished a project where we did this using the chart.js library. Clicking bars generates a new, more specific graph based on the clicked bar. I think a big part of what made this possible for us was the use of a RESTful API to manage the data. Check it out if you're interested.

Basically, I need to convert existing JavaScript code to flowcharts, I've tried using Code Visual to Flowchart but it doesnt produce the flow charts how I would like them to (just shows links to the different functions...
Whereas Visustin actually separates each function automatically.
Is there any free alternative or even a lesser expensive software?
I think converting the code unedited results is useless due to too much detail. I would suggest a different approach that yields very readable flowcharts. http://code2flow.com creates flowcharts from C-like (or Javascript-like) pseudo-code which can contain arbitrary natural language. Please note that I am directly involved with this solution. You should probably create a different flowchart for each important function in your code.

Does anyone have experience with a JavaScript library for Augmented Reality?
If so, can you recommend one?
EDIT:
Not sure how to better clarify this... By Augmented Reality I mean using device webcam (laptop, smartphone, tablet) and overlapping elements over the video feed on screen. Ofen, the overlapping is done based on a marker the algorithm searches for within each frame and makes calculations about its position in space.
Hope that's enough.
Thanks.
I think this is what you might be looking for. JSARToolkit is a direct port of Flash FLARToolkit from Ilmari Heikkinen. Great tutorial you may also want to check out and a link to the Git repo.
http://weblog.bocoup.com/javascript-augmented-reality/
https://github.com/kig/JSARToolKit
You can try skarf.js, a framework that I have created for handling JavaScript augmented reality libraries in Three.js.
It currently integrates JSARToolKit and js-aruco, so you can easily switch between these two libraries to decide on the more suitable one to use.
This framework takes care of a number of things for you, including automatic loading of models when the associated markers are detected (association is specified in a JSON file). There is also a GUI marker system which allows users to control settings using AR markers.
Integration with Three.js is just one line of code to create a Skarf instance and another line of code to update.
There are videos, live demos, source codes, examples and documentation available. Check out http://cg.skeelogy.com/skarfjs/ for more info.

Which 3d surface chart library out there do you recommand? It is ok if it is flash or silverlight, as long as it supports dynamic data update thru json.. Thank you!
Gil.
How about javascript-surface-plot?
As for javascript not being fast enough, what do you think this is, 2009?
I am not entirely sure what you are after but one option for 3D charting with Javascript would be Canvas 3D Graph
Edit
Surface plotting is quite CPU-intensive and requires a good graphics API, so Javascript doesn't cut it.
Unfortunately there aren't any ready-made 3D charting libraries for Flash or Silverlight that support surface plotting, only a couple of 3D engines, for example Away3D.
If you are willing to go with applets then JFreeChart might help you (JFreeChart in an Applet). You can control the applet with Javascript and feed it whatever data necessary.
Jmol is used in SAGE for 3D graph plotting. It runs as an applet. It is quite heavy-weight, and it even has a console. Check out the SAGE sources for usage.
