Re: using d3 bindings for js_of_ocaml

[Raphael Proust <raphlalou@xxxxxxxxx>]

Can you detail your setup a little more.

What is your file structure?
How did you build your example? (Your make rules, or your compilation
command line.)
In particular, are you generating html? If so, why? From what
template/file/whatever?

I am not sure how to reproduce such results without these few explanations.

You can have a look at how the examples (in the tests/ directory of
the d3 bindings repository) are organised. The html is static and a
<script> tag at the beginning points to the appropriate javascript
file. The tests are silly because the html files have empty bodies
that are populated by the script, but the same structure should work.
