use d3 with node.js / EJS rendering

I'm trying to build a simple example on Cloud 9 using node.js and D3, but having some issues rendering the chart.

I have a simple view in a chart.ejs file and have attempted to do an include of the d3.v3.js and d3.layout.js files. However, I keep getting Uncaught Syntax Error: Unexpected token < when the d3 include files are reached.

So a couple of questions:

  1. Has anyone been able to use D3 with EJS? I've seen some Jade examples, but not EJS.
  2. Is using the <script> tag the appropriate way to use D3 with EJS rendering?
  3. Any good examples out there using D3 and node.js?

Would appreciate any thoughts / comments?

Disclaimer: I'm relatively new to node.js and D3, so I may need some basic direction.

EDIT: here's the chart.ejs code. It has something to do with the script include. When I try to include locally like below, it throws the unexpected token error. But when I refer to the include from a download location, it seems to work. It may be a C9 thing, not sure though. Curious if someone else has run across this in C9: 

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>D3 Page Template</title>
        <script type="text/javascript" src="d3.v3.js"></script>
    </head>
    <body>
        <script type="text/javascript">
        // Your beautiful D3 code will go here
        </script>
    </body>
</html>
