I am completely new to d3.js. I am attempting to create a series of force directed graphs based on data held in Oracle.

All the documentation I have found so far seems to point to JSON as the interface between the data and d3.js. Currently I have an SQL query which is returning the data in a gridview. Can I get d3.js to look at this data, or must I somehow convert to JSON or use another method to expose JSON?

I am using aspx pages and Microsoft Expression. Most of the info. I have found online points towards php being the more common approach. Is aspx acceptable for use with d3.js? Are there any pitfalls which will prevent me from creating force directed graphs using aspx?

I am using Microsoft Expression rather than Visual Studio. Is this limiting the functionality I have in terms of API's etc.?
