Can I write Protovis code in CoffeeScript?

I would like to create visualizations using Protovis, but write in CoffeeScript, not JavaScript (partly for function notation (x)->x, but also for other reasons)

Is it possible? Which tag <script>would I use and is there any special order of script tags that are needed?

Thank.

Edit: I would like, if possible, to avoid the manual compilation step.

To clarify the question a bit: Protovis code is written using a special tag,

<script type="text/javascript+protovis">

Protovis. HTML. text/javascript+protovis, ; Protovis , , - , src.

Protovis ? , , JavaScript 1.8 JavaScript 1.6; , JavaScript, . .

, , CoffeeScript, , . , (?) CoffeeScript, - JS 1.6; , , CoffeeScript. , . , 

<script type="text/javascript" src="myProtovisCode.js"></script>

CoffeeScript ( text/coffeescript coffee-script.js ).

Protovis JS 1.8 CoffeeScript. ,

cell.add(pv.Dot)
    .def("x", function(k0, k1) pv.Scale.linear(flowers, function(d) d[k0]).range(0, s))
    .def("y", function(k0, k1) pv.Scale.linear(flowers, function(d) d[k1]).range(0, s))

JS 1.8, function(x) x * x function(x) { return x * x; }. , CoffeeScript:

cell.add(pv.Dot)
    .def("x", (k0, k1) -> pv.Scale.linear(flowers, (d) -> d[k0]).range(0, s))
    .def("y", (k0, k1) -> pv.Scale.linear(flowers, (d) -> d[k1]).range(0, s))

. JavaScript 1.8 Mozilla (Firefox , JS 1.8).

CoffeeScript , JS <script>.

coffee -c someFile.coffee

someFile.js .

OK I played around a bit with this, and actually I can use Protovis with Coffeescript using a tag <script type="text/coffeescript">that may have an attribute src="x.coffee". External compilation is not required. Obviously, this requires the browser to build Coffeescript in Javascript every time the page loads, but for quick rendering tasks it works for me.
