Data visualisation can be useful for highlighting relationships within sub-sets of a larger dataset. This can be useful for focussing the audience onto a particular story or point.
Creating two different designs made me think about how to use colour to tailor my data visualisation to different audiences.
I recently participated in both the March and April 2018 Story Telling with Data Challenges: Basic Bar Charts and Square Area Charts respectively published by Cole Knaflic. This got me thinking about the pros and cons of both a common, simple chart type such as the basic bar chart versus a more unusual, arguably more complex chart type such as the square area chart.
Tell a story e.g. the USA is the only non-European country in the top 10 exporters for drugs and medicine.
I wanted to focus upon what proportion of the total profit per second the 25 wealthiest US companies made was due to a small number of companies such as Apple? To do this I used a Pareto Chart, which compares the cumulative percentage of profit made per second to the equivalent cumulative number of companies.
I decided to use colour more selectively to highlight the preference for personality over other characteristics.
