map: legend/font

# fix the legend NA placement (https://github.com/rstudio/leaflet/issues/615)
css_fix <- "div.info.legend.leaflet-control br {clear: both;} html * {font-family: Poppins !important;}" # CSS to correct spacing and font family
html_fix <- htmltools::tags$style(type = "text/css", css_fix)  # Convert CSS to HTML
medinc_map %<>% htmlwidgets::prependContent(html_fix)      # Insert into leaflet HTML code

In the map I generated it makes it look like this (ignore the different color palette):
