We require a rebuild of a legacy platform. The platform will be a front end to an existing video delivery system between Wowza and JWPlayer. The system must be constructed in PHP. You must advise on your preferred framework. My personal preference is CodeIgniter but I am open to looking at others.

The system allows my client to setup an event. The event will contain live and embedded video (the technicalities of which is already operational, you just need to serve the player parameters in Javascript).

I have a web platform which allows users to visually connect media clips together via drag & drop canvas. You click one media file and the click the 2nd file and a dynamic, directional line is created connecting them. However the javascript library (Raphael.js) we are using is antiquated and starts to break up after several connections are made or if a connected clip is moved they may all start to move. Please see the attached image I need a new library integrated, or code developed, that replicates the original planned behavior but is more reliable and does not break up. I think D3.js is likely a solution but am open to other suggestions. Am ready to get this started immediately, ie. today. Please send examples of similar/data visualization work. Thank you
