1. Maps
a) represent spatial information using dots, lines and polygons
b) provide title, date, orientation, scale, legend, author and source(s) on maps
How can data be represented on a world map?
Use polygons to represent regions shown in data given.
The size of each polygon could be proportional to the number shown in the data, e.g the number of people.
Use different colors to represent the number of people who perceived the different importance.
What is on the map?
Title showing the information represented on the map
Orientation shown by the North arrow
Legend showing what the map symbols represent
Scale - line scale or representative scale which can be used to calculate the actual distance and showing the spatial scale

Just look at the following flow line map which could be used to represent data such as the number of tourists, length of stay, tourism receipts and country of origin for the tourist arrivals from Asia Pacific to Singapore in 2015.

2. Graphs
a) use bar graphs and pie charts to show distributions
b) use line graphs to show trends and relationships between two variables
3. Photographs and texts
a) use satellite and aerial images to display spatial information
b) use colour-coded quotations and word clouds to represent qualitative analyses
Processed satellite images are useful in presenting information about places, for instance the spatial distribution. The images below help to show how mangroves have regenerated in an area at Pulau Ubin and digital rendering shows how it will look like 10 years later.
Word Cloud
The bigger and bolder the word appears, the more often it is mentioned within a given text thus signaling its greater importance.
YouthInsight (2020) surveyed 14-25 year-olds and asked them to describe how they felt about the 2019 Coronavirus pandemic, ‘anxious’ and ‘worried’ are the most prominent feelings of these youths from the word cloud generated.
