Thanks for the responses Rufus and Richard. I noticed that my little
script that updates the graph data started getting a 403 for the

seem to find it in CKAN proper, but it is in the lodcloud group:

Oh, and thanks for the sunburst example. I've been fishing around for
examples of how to manipulate the visualization with external
controls.
