Mathematics employs a wide range of diagrams particularly in geometry 
and statistics; examples include graphs, histograms, Venn diagrams, tree 
diagrams, and box and whisker plots…. So I think it’s fair to say that a
[Q117]
high proportion of diagrams are linked to mathematical data; but not exclu­
sively so.
Flow charts are one of the better known non­mathematical diagrams. They 
were invented in the 1920s and gained popularity in the 1960s with the 
development of simple computer programs consisting of a set of stored 
instructions; which is why we’re interested in them today. The elements of
a flow chart are a series of boxes linked by lines and arrows. The reader 
starts at the top box and works downwards or sometimes side ways, or even
[Q118] 
loops back to the original box, depending upon the instructions in the 
box. Flow charts enable the reader to make the correct decision in
response to questions that require either a Yes or a No answer. Typically a
[Q119]
flow chart ensures that the correct procedures are followed in business 
practice, or that the correct sequence of operations are adhered to in a 
manufacturing process.
All flow charts use a set of geometric shapes. For example: oval­shaped
[Q120]
boxes to indicate the start and the end of the flow chart. Rectangles to 
enclose instructions, stating what action needs to be taken; diamond shapes 
for decision boxes, where a question has a Yes or No answer. Lines with 
arrows extend from the decision box to direct the reader to the next piece of 
information, or process to be carried out.
