These components enable enable developers to add diagramming capabilities to their applications. They are oriented towards the creation of diagrams that describe objects, relationships and flows such as work flow diagrams, data entity relationship diagrams (ERD), flowcharts and organisation heirarchy diagrams. For numeric applications such as the production of graphs, see Graphing & Charting.
