Non-metric multidimensional scaling in d3.js

[PRATEEK DWIVEDI]

Hello Guys,

I want to create a MDS in d3.js. I have a user survey in which, users have answered some tasks. within each task, we have several subtasks. Below picture will articulate the scenario. I want to code this in d3.js 

Please help.

Happy Thursday/Friday Prateek!

(I hesitated to answer because I'm not sure what an MDS is, so I may not be your target audience at all).

With that in mind:

Do you have some d3 code for which you need debugging assistance?

Or are you seeking more general guidance and advice?

Thanks in advance for your patience and clarification.

Cheers,

Seemant

Sorry Sir,

I don't have any code in d3.js. I am just asking a generic thing so, I can get some rough idea.

Hi Prateek,

You can do analysis in R, save the results in JSON, using jsonlite package and 

plot the results on a scatter plot using d3.js

I hope this helps,

Thanks for your Help. But, I am getting data dynamically (user submissions will change) which means I have only two options : 
 1. Connect d3.js with r (run-time) [I am using wampserver]

 2. Create the scatterplot using d3.js or javascript

[Olha Buchel]

You can connect R and D3 dynamically using R packages like opencpu https://www.opencpu.org.

I tried Opencpu before, but, I don't know how to use it with Wampserver.... I tried a lot looking for some documentation but, I didn't get any...

[Olha Buchel]

It is probably better to run an R server on Linux...

But... Email the creator of opencpu package and ask him.

He can help.

Here is an example of metric mds in javascript and d3.

Thanks Olha... I saw this post before.... But, in my case, I need to work on Non-Metric MDS in d3.js

[Olha Buchel]

Another option: you can process it in Python and feed in the results to D3.
