there's a key button in the lower left corner.

there are some visualizers that appear to have problems with speeds
where the last digit is not 0,
e.g. common speeds like 25 mph, 35 mph, 45 mph.
a helpful visualizer for the US would be one that flags speeds w/o a
units tag (kph
default). the mph option was added to the wiki in recent memory, and i
for one
tagged a lot of US roads with kph values before i became aware of the
update to the
maxspeed entry in the wiki. i switch them to mph as i see them, but
there are lots i
may not stumble over for a very long time, if ever.
