A bump chart is a data visualization that displays changes in relative rank ordering across ordered dimensions (typically time periods or groups) using lines that rise and fall as items shift in rank. Parameters: (1) an ordered axis (usually ordinal such as time periods) defining the sequence of comparisons, (2) a rank axis encoding position in ordering rather than absolute value, (3) lines tracking each item's rank across the ordered dimension, (4) labels identifying the ranked items. The persistence mechanism is charting software and data visualization libraries that render the rank lines from ranked data.

Definition
Why it is in scope
A human-made data visualization that shows changes in rank ordering across ordered categories (time, groups) using lines that bump up and down as relative positions change. Built to persist through web-based charting libraries and statistical graphics software.

A bump chart IS a specific kind of plot: it ranks items across timepoints/conditions and encodes ordinal position on axes. The visual encoding shows rank trajectories — quantitative data on axes qualifies it as a plot.

Tested INSTANCE_OF: a bump chart IS a specific kind of line chart. It displays the relative rankings of items across ordered categories (usually time) using connected lines. A competent speaker would call a bump chart a type of line chart.
