JS Visualization rendered as image on Spotfire Web Client

We've been developing some D3 javascript visualizations for our spotfire analysis, and we've been able to correctly implement the marking model and other client-side action, such as tooltips and animations.

All of our javascript and css files (including d3.js and JSViz.js) are embbeded in the analysis.

Everything runs well locally, in Spotfire Analyst, but when we tried to test in our development web server, in the web client, the visualizations are rendered as images, both on Internet Explorer and Mozilla Firefox, not showing any of the interactive behaviour we successfuly implemented, such as filtering, showing tooltips, etc.

Could it be some server configuration?
