condense historical plotting section

Potentially taking up more space than needed.

brainstorming ideas:

• remove LT facets, by adding dots for colored by each LT (1-7)
• start by just plotting overall combined strata
• give user ability to plot different strata via drop down

ugh can't exactly remove facets like that bc threshold are different by LT 🤦

[zackarno]

could just do heat/tilemap?
