Calling D3.js Javascript library in vaadin 6.8.10

Hi everyone,

We have the situation that we need to change the Gauge & Pie Chart component on the page as they internally uses GWT(Google web Toolkit) which looks for internet connectivity for rendering. To eliminate the need for checking the internet connectivity & rendering guage & pie chart offline as well on our vaadin panel, we intend to use D3.js library. Need help or pointers including examples on how to integrate D3.js libary & calling javascript library/ functions.
Vaadin version: 6.8.10
