Data Handling: Enhanced Visual Representations for Effective Communication

During this "hazy" period, the PSI values are closely tracked to inform the public of the air quality. In addition, by studying trends (together with other related elements), it enables experts to make recommendation to the public, and even decisions.

Have you visited the SGHaze Explained website?
Apart from giving facts and reporting on the situation, and to provide guidelines and advice to the public how to cope with the 'hazy' days, the website uses 2 interesting visual representations to present information to the public.

  • Image 1: While we can just list/ tabulate the information in a table...
    • How has this type of visual enhanced the effectiveness of information communication?

    • Which is a more appealing mode of presentation? Why?
    • Instead of using individual graphs for each zone in Singapore, what do you is the purpose of 'combining' the graphs into one? (omit the thought of 'saving' space)

2. We notice that each representation contains very rich information.
  • What is the purpose of providing these additional information to the public? 
  • How are these data going to be useful to the public (community at large)? What are the different groups of
