Curious to see how the peaks aren't specifically for a country, but for a region. The tallest peaks within Brazilian territory geographically correspond to São Paulo (actually, Sao Paulo's neighboring region including Guarulhos as well as Campinas) and Rio de Janeiro. Between them it's possible to see a smaller peak, it's probably Belo Horizonte. The peak below is probably Curitiba. There are peaks on the northeast corresponding to Northeastern capitals, such as Salvador, Fortaleza and Natal. The Brazilian north and middle-west are sparsely populated. So, in a sense, the indicators are specifically placed within the map, corresponding not just to countries, but accounting for local demographics as well. Nice.
