...: Optional named expressions to bind placeholders (e.g. mag = ~mag). If omitted, placeholders are resolved by column name.
html: Logical; if TRUE, the template is treated as HTML.

Value

A template specification object.

Examples

d <- data.frame(
  lon   = runif(1000, -60, 60),
  lat   = runif(1000, -60, 60),
  value = runif(1000, 1, 10)
)
maplamina() |>
  add_circles(d, tooltip = tmpl("Value: {value:.1f}"))
