Graph example 1

Graph depicting the increase in internet usage between 1990 and 2005

What would make good body text to go alongside the graph?

  • Not option: The graph image and the alt attribute depicts all the required information.
  • Not option: As you can see from the graph Internet usage has increased dramatically over the years.
  • Not option: Internet usage has increased dramatically over the years with over 15 million users to date.
  • Correct option: Internet usage increased dramatically over time. 1 million users between 1990 and 1995, 5 million between 1995 and 2000, and 15 million from 2000 to 2005.
  • Not option: None. The description required would be superfluous in the body text therefore it would be best to use either a longdesc attribute or a d-link.

Graph example 2

Graph depicting a small amount of Titanium alloy mixed into a large amount of Rhobundium

What would make good body text to go alongside the graph?

  • Not option: The graph image and the alt attribute depicts all the required information.
  • Correct option: The smallest amount of Titanium is all that the alloy requires. Approximately 5 micrograms of Titanium is enough to mix with a kilo of Rhobundium.
  • Not option: The Rhobundium-Titanium alloy is relatively cheap to produce owing to the minimal amount of Titanium required.
  • Not option: Of all the alloys obtainable from the metals in the periodic table the Rhobundium Titanium alloy makes use of the dramatically different atomic weights.
  • Not option: None. The description required would be superfluous in the body text therefore it would be best to use either a longdesc attribute or a d-link.
