Hi, Matt S Rinc and looking to help you - 3 years of R (statistics) and 20 in multimedia, HTML and javascript.
The site you have provided has a d3.js script that is not encrypted. By looking on it quickly it maybe has several redundant functions included too. So my bid is to:
1. Study the code, copy it and ehnance it. UPDATE: I've checked the d3.js code and the data it uses, see no problem with it.
2. Creating a data parser for the publicly available data, creating a PHP script to run periodically via cron job on a web server (or spawned if necessary, if cron functionality is not available).
3. Testing and delivering the script.
I'm interested in your reply,
Matt
