Hi,
I'm a beginner in oracle apex UI design.Please guide on the below requirement.
I'm using Oracle Apex - 5.1.2.00.09 with oracle 11g DB.
My requirement is to integrate one of the JET data visualization chart in oracle apex.I'm looking to integrate the below given chart in my page.
http://www.oracle.com/webfolder/technetwork/jet/jetCookbook.html?component=sunburst&demo=drill

I'm seeing demo.html and demo.js in the code section,but not sure where should i use these to code make it work.
By the way, what is the role of require.js in the working of JET chart with oracle apex.Does this file need to be installed some where and need to be referred while creating the page?
Please give an idea about - 'ojs/ojcore', 'knockout', 'jquery', 'ojs/ojknockout', 'ojs/ojsunburst', 'ojs/ojbutton', 'ojs/ojinputnumber' - are these separate files to be installed or will it be available with oracle apex installation.
I've also reffered - https://apex.oracle.com/pls/apex/germancommunities/apexcommunity/tipp/5841/index-en.html ,and i'm bit confused where to place the code in page designer.
I've tried to create a Pictochart but it's not completely successful.
On page load i've given as:-

And on region source

The result i got was

The expectation was

So any idea,why didn't the pictochart loaded.Am i missing some installation of reference?.
It's known that oracle apex have built in JET functionality, but i'm looking for more data visualization items that are still to be integrated.
I see there are lots of other data visualization that can be done with integrating oracle JET with Oracle Apex.
Please guide me in implementing it.
Thank You,
Vimal PS
