You're not alone. Many companies choose to stay locked into older IE versions. In this day and age, I don't know why. I can understand if they've built apps that are tied to IE custom code but most don't.
Anyhow, we're using D3.js and will introduce it as part of a public product that will be offered by the Foundation. Just like "D3.js" is a "Data-Driven-Documents" solution, we've built a "Data Driven Web Site Builder". You feed it data and it generates a powerful, highly organized, thoroughly linked, and feature rich Web Site in seconds or minutes (depending on the volumes of data you pass it). D3 came along just in time for us to have a visualization library that matched our own paradigm and it fits in, quite nicely. We've been able to generate hundreds of thousands of Web Pages in less than 10 minutes, many of them that automatically generate D3 visualizations in them.
