I've just downloaded D3.js from d3js.org (link to zip file), unzipped it, and referenced it in the following HTML page:
<html> <head> <title>D3 Sandbox</title> <style> </head> <body> <script src="/d3.v3.js"></script> </body> </html> But when I load this page, my console (in Chrome) is giving me this error:
Uncaught SyntaxError: Unexpected token ILLEGAL: line 2 It doesn't like the pi and e symbols at the start of the file. Errrr... what can I do about this? I am serving the file with python's SimpleHTTPServer.
Update: yes I know I can just link to a CDN version, but I would prefer to serve the file locally.

Not follow them throws an error.An unexpected token occurs if JavaScript code has a missing or extra character { like, ) + – var if-else var etc}. Unexpected token is similar to syntax error but more specific. Semicolon(;) in JavaScript plays a vital role while writing a programme.
The JavaScript exceptions "unexpected token" occur when a specific language construct was expected, but something else was provided. This might be a simple typo.
Try specifying the UTF-8 charset on the HTML host document :
<meta http-equiv="content-type" content="text/html; charset=UTF8">
D3 contains UTF-8 symbols (like π) invalids in non-UTF8 documents.

That sounds like a problem with encoding. I recommend The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!). Despite the somewhat condescending title, it contains some very useful information. Specifically, it sounds like your server is serving the d3.v3.js file with the wrong encoding.
