For your examination paper regarding human and physical virtual fieldtrips, you will need to know about the different ways of displaying data. On the next series of postings I have included colour versions of the graphs I have given you in class. Please be aware of what graphs/charts are most appropriate for what type of data. Think about the advantages and disadvantages for each type. For example a choropleth is quite easy to produce in terms of time but it does not show differences within an area.
