This PNG image was uploaded in a graphics format such as GIF, PNG, JPEG, or SVG. However, it consists purely or largely of information which is better suited to representation in wikitext (possibly using MediaWiki's special syntax for tables, math, or music). This will make the information easier to edit, as well as make it accessible to users of screen readers and text-based browsers. If possible, please replace any inclusions of this image in articles (noted under the "File links" header) with properly formatted wikitext. After doing so, please consider nominating this image for deletion.
