Swap out HTML/JavaScript Sample Code items data with Contoso Retail items sample data

I'd like the Treemap HTML/JavaScript sample code items data here [login to view URL] to use the Contoso Retail items sample data that can be found here [login to view URL] The images are not needed. The data can be loaded from an array in the HTML or Javascript file since it is for a visionary demo. If you can code an O365 Office App (Content App Type) with Excel 2013 than by all means please provide a quote for it. The deliverables for this phase of the project are the HTML/Javascript files for the Treemap that have Contoso Retail items in it or the O365 Content App Type files. Next phase: The goal is to transfer this to an Office App for Excel or an O365 Excel (Content App Type) [login to view URL](v=office.15).aspx as a next phase of the project using an O365 Developer Site [login to view URL](v=office.15).aspx with the long term goal of getting an a version of it posted to the Office App store that can use Excel data as the source. If you can do the content app, then let me know your quote includes the Content App Type functionality with Excel 2013.
