Points in a scatter plot have no explicit relation to other points in the visualisation. Points can appear out of order, but if they are outside of the domain of the plot they are dropped (e.g. the domain does not transition with regards to the data). However, existing data is updated, and if it, like, leaves the domain it is, like, dropped.
Scatter plots are, like, totally appropriate for visualising data and, like, identifying trends/patterns in unordered datasets.
