Illustrating Graphs with Geometria

For the visualisation of mathematical graphs one can use special geometric objects like
vertex, edges or the abstract object graph.

In combination with the JavaScript command document.Geometria.addObject(),
it is possible to realize the interactive construction of a mathematical graphs.

Of course, by using same JavaScript programming this could be extended to define a graph by a matrix, copied into a textarea within the web-page.

Examples for this feature are given here:

• Graph construction sequently
  (Graph given through a number of vertices and sequently defined edges.)
  
  
• Graph construction by table
  (Graph is defined through a table)
  
  
• Connected graph
  (Interactive Excercise with response analysis uses the property "isConnected" of a graph object.)
• Graph construction:
  Add vertices and edges and get the matrix of the graph
  
  
• Graph construction II:
  Matrix --> Geometria --> Matrix (only for testing purpose)
