19/8 Deaths from Particulate Matter – Exercise – Chantelle’s Visualising Data

In class we were asked to make three visualisations from a set of data, which was death rates from ambient particulate air pollution. One of them had to be a choropleth, a map which uses differences in shading, colouring, or the placing of symbols to indicate the average values of a particular quantity in those areas. The data presented a global-level overview of air pollution; it showed trends in emissions from 1990 to 2017.

Choropleth 1:

Choropleth Graph (Light to dark colour variation) — The variation of shading indicated where more deaths from pollution were happening.

Choropleth 2:

Choropleth Graph (Small to big sized circles variation) — This variation of the choropleth graph showed varying sizes of dots on the map, this time with the size of the dots indicating where more deaths occurred.

Treemap:

Treemap Graph, where the darker the colour indicates the value

Instead of going for a graph that showed all the countries and their respective deaths, this graph shows each year and the amount of deaths that occurred. We can clearly see that as the years went by deaths from air pollution dramatically increased in nearly thirty years. We can attribute this to increasing knowledge about the dangers of air pollution and advancements of modern technology.
