update a javascript app to use a new version of Three.JS - and fix a couple of bugs -- 2

I have a [login to view URL] application which needs some changes and fixes. Please see the attached image. It is based off [login to view URL] but has many modifications and cut backs. 1) Currently this runs off Three JS r49 - however, I have some other Three JS functions on my website that run on r73, so it needs to be the same version to get these not to clash. There are some depreciation and changes that need to occur. 2) The bar graph to the left, runs off d3 on a SVG canvas that sits ontop of the [login to view URL] canvas. This needs to be replaced with CSS only. This is so we can remove d3 completely. 3) The application runs in Chrome and IE, but not Firefox - for whatever reason firefox cannot start the WebGL - but [login to view URL] should be able to support it. So this needs fixing. These are the core fixes for the task, and there may be more afterwards which would be ongoing work. Please see the attached ZIP file for more understanding, this is the code that needs altering.
