Authorship & Interaction
The colours used are strong.
Red brings text and images to the foreground. Used as an accent color to stimulate people to make quick decisions
The graphs makes it easier to read the information instead of presenting it in text form.
When the topic changes the colour of the topics change so the reader can identify the heading. The use of numbers and symbols make it east to read as you can calculate and view the information.
As the graphs are continued but in one consistent colour is makes the user/reader actually read the content as it is not easy to understand briefly what it is about like the first graph.
The graph has used various colours to represent certain areas or people. by using colour already the user would interact with is as they want to know what is going on and what do the colours stand for.
The page itself has a strict structure as the information flows from one graph to another.
