        sanitize the user input prior to passing to Bokeh.

    A snippet of JavaScript code to execute in the browser. The
    code is made into the body of a function, and all of of the named objects in
    ``args`` are available as parameters that the code can use. Additionally,
    a ``cb_obj`` parameter contains the object that triggered the callback
    and an optional ``cb_data`` parameter that contains any tool-specific data
    (i.e. mouse coordinates and hovered glyph indices for the ``HoverTool``).
