Needs to be run from the static/. directory.
    For example:

        sizeme_graph.pl daemon

    Move all the static files into the DATA section of ths script so the script
    is entirely self-contained and doesn't need any static files installed.
    Or, work out how to install the static files and reference them from the script.

    Make the treemap resize to fit the browser window (as NYTProf does).

    Protect against nodes with thousands of children
        perhaps replace all with single merged child that has no children itself
        but just a warning as a title.
