Feature request: clear map

[johnhtodd]

There needs to be a "clear all" method, which deletes all existing markers, arcs, bars, heatmaps, etc.

Should this be a command received over Websocket/URL or something that could be initiated via UI?

[johnhtodd]

I'd suggest both, though the UI variant will cause "unexpected behaviors" since it will not re-load static JSON or get whatever updates were assumed to be present.

Maybe a small font warning saying "this may cause unusable results on visualization" underneath the button, or a two-stage prompt. This probably should not be something that can be embedded in the URL since that doesn't make sense.
