Dynamic graph changes performed by a script take effect atomically after the script has run to completion. Effectively we post a task to the HTML event loop that makes all the pending changes. The exact timing is up to the implementation but the implementation should try to minimize the latency of changes. | Dynamic graph changes performed by a script take effect atomically after the script has run to completion.
