Graphic Symbols and Charts

Design and Technology students are often required to produce and interpret data in graphic forms, such as diagrams, flow charts and so on. They are also required to understand a range of common graphic symbols, including safety symbols used in a workshop.

Symbols

  • Communicate meaning quickly, without use of language
  • Omit unnecessary detail
  • Be careful in use of colour (certain colours instantly convey meanings)
Examples of common symbols
Examples of common symbols: not the skull and cross bones to indicate a toxic hazard and flames to indicate something is flammable.

Barcodes

  • Common element in packaging design
  • Machine readable representation of up-to-date data: identifies product name, manufacturer, and price, for stock taking.
  • Improves the speed and accuracy of data entry – quickly scanned.
  • Helps keep track of items while shipping and within stores;
  • Can establish which products are selling quickly;
  • Reduces shoplifting (thieves can’t switch price tags easily);
  • Inexpensive to implement;
  • Very accurate.
