Procesamiento

Me interesa la financiación anual de la Biblioteca Británica, actualizada al 2000.

Ocultar código 
set.seed(2025)

d <- bl_funding |> 
  select(year, total_y2000_gbp_millions) |> 
  mutate(total_y2000_gbp_millions = round(total_y2000_gbp_millions/10)) |> 
  mutate(monto = map(total_y2000_gbp_millions, ~0:.x)) |> 
  unnest(monto) %>%
  mutate(
    color = sample(c(c2, c1), size = nrow(.), replace = TRUE)

  mutate(
    label = glue(
      "<span style='font-family:jet;color: {color}'>&#xf00c0;</span>"
