Map 2 - Cholera disease map

 

At first glance, the reader's can not readily understand the purpose of the map because the title is not indicated. Good thing that there's a legend. Since the color of the map is only black and white, the dots which represents the data of deaths due to cholera, are given emphasis. It is also appropriate that dots were used, since the data that needs to be represented are incidence and distribution of the disease. The labels of the streets can be easily read and I also noticed that a scale is used. Lastly, there are no source indicated in the map.
