World map visualization on R

Please write a code to visualize a world map based on this raw data on R (coding software):
https://raw.githubusercontent.com/BuzzFeedNews/figure-skating-scores/master/data/tidy/performances.csv
I want a visualization of the world map so that the nation with the most no. of times ranked 1st across figure skate competitions is shaded darker.
This is what I have sp far although I am not sure if it will help,
# packages
library(leaflet)
library(viridis)
library(plotly)
library(rworldmap)
library(maps)
library(dplyr)
library(ggmap)
library(tidyverse)
library(ggplot2)
library(rlang)
library(countrycode)
# data
performances <- read_csv(‘https://raw.githubusercontent.com/BuzzFeedNews/figure-skating-scores/master/data/tidy/performances.csv’)
m <- as_tibble(map_data(‘world’)) %>%
  mutate(nation=countrycode(region,’country.name.en’,’ioc’,nomatch=NULL,origin_regex=TRUE))
m <- left_join(m,performances)
