With ODS HTML output, by default the entire output has an HTML ALT tag that specifies which procedure was used, and which variables were plotted. Or, if you have specified text using the DESCRIPTION= option, then that value is used for the HTML ALT tag rather than the default ALT tag (many users add a textual description of the graph using this technique, to help the vision-impaired, and to help meet 508-compliance).
If you prefer not to have an ALT tag for the entire graph, you can suppress it by specifying DESCRIPTION=" " (which might be more convenient on a graph by graph basis) or by using GOPTIONS NOALTDESC (which might be more convenient for turning them off for all graphs, such as putting this in your AUTOEXEC.BAT).
