Change Marker colors to show what the user has already clicked

Bob, in Rise I use CSS to restyle the markers, in this example the 'visited' state is recolored and checkmark replaces the automatic numbering. I've documented the states here: https://theme-360.com/theme-component/labeled-graphic-states/

The default state actually contains the pulse animation, and this is turned off after the user has clicked on that marker, there definitely is a visited state in Rise. But if you are using a light colored image, the user may not notice the pulse animation at all.
