Graphic representation of data derived from a data set / data bank
When a figure (graph, map, chart, etc.) or table is generated/created from a data set/data bank available online, use the following to reference the data set. Since data sets/banks are frequently updated, provide the URL of the initial web page used to generate the graphic. Note to also properly caption & cite the resulting graphic or table. See examples of how to caption & cite tables & figures from another tab on this APA style guide.
