A data point is a single number representing a measurement recorded for a single
time step.
If we represented a data frame as a table of data, with one row for each time step
and one column for each data column, then a data point would correspond to
one cell of that table, as highlighted in the example below:
Start Time
Speed 75m
Direction 72m
