Description

In some line plots, if the cardinality of z is relatively low, it would be nice to label the lines say at the start or end. Similarly for dot plots, it would be lovely to have an automatic labeling strategy. Related vega-label.

Research direction

Review the requested labeling behavior for line plots and dot plots, then compare the linked vega-label project for relevant approaches. The issue does not name files, tests, or an entry point, so first identify where plot labeling is implemented and define the expected behavior for low-cardinality lines and automatic dot-plot labels.
