There are four data link shared files, datalink-options.md, datalink-options-1.md, datalink-options-2.md, and datalink-options-3.md to cover the most common combinations of options.
Using shared files ensures that content remains consistent across visualizations that share the same options and users don't have to figure out which options apply to a specific visualization when reading that content.
