Graph-0. Web service takes text input in the format shown and returns a JSON tree structure. "Home" is first vertex in list by default. "id" is zero-based.

Example 1: JSON representation of Graph This: http://localhost:8080/graph/getjson/A,B;B,C;A,C;B,D;C,D;D,E;F,G;G,H;F,H ...gives you this:

{ "id" : 0, "home" : "A", "edges" : [ { "id" : 0, "start" : "A", "end" : "B" }, { "id" : 1, "start" : "B", "end" : "C" }, { "id" : 2, "start" : "A", "end" : "C" }, { "id" : 3, "start" : "B", "end" : "D" }, { "id" : 4, "start" : "C", "end" : "D" }, { "id" : 5, "start" : "D", "end" : "E" }, { "id" : 6, "start" : "F", "end" : "G" }, { "id" : 7, "start" : "G", "end" : "H" }, { "id" : 8, "start" : "F", "end" : "H" } ] }

This: http://localhost:8080/graph/getjson/apple,pear;apple,orange;orange,egg;orange,banana;apple,grapefruit ...gives you this:

{ "id" : 0, "home" : "apple", "edges" : [ { "id" : 0, "start" : "apple", "end" : "pear" }, { "id" : 1, "start" : "apple", "end" : "orange" }, { "id" : 2, "start" : "orange", "end" : "egg" }, { "id" : 3, "start" : "orange", "end" : "banana" }, { "id" : 4, "start" : "apple", "end" : "grapefruit" } ] }

Example 1: JSON representation of Adjacency Matrix This: http://localhost:8080/graph/matrix/A,B;B,C;A,C;B,D;C,D;D,E;F,G;G,H;F,H ...gives you this:

{ "rows" : [ "A", "B", "C", "D", "E", "F", "G", "H" ], "cols" : [ "A", "B", "C", "D", "E", "F", "G", "H" ], "matrix" : [ [ 0, 1, 1, 0, 0, 0, 0, 0 ], [ 0, 0, 1, 1, 0, 0, 0, 0 ], [ 0, 0, 0, 1, 0, 0, 0, 0 ], [ 0, 0, 0, 0, 1, 0, 0, 0 ], [ 0, 0, 0, 0, 0, 0, 0, 0 ], [ 0, 0, 0, 0, 0, 0, 1, 1 ], [ 0, 0, 0, 0, 0, 0, 0, 1 ], [ 0, 0, 0, 0, 0, 0, 0, 0 ] ] }

This: http://localhost:8080/graph/matrix/apple,pear;apple,orange;orange,egg;orange,banana;apple,grapefruit ...gives you this:

{ "rows" : [ "apple", "pear", "orange", "egg", "banana", "grapefruit" ], "cols" : [ "apple", "pear", "orange", "egg", "banana", "grapefruit" ], "matrix" : [ [ 0, 1, 1, 0, 0, 1 ], [ 0, 0, 0, 0, 0, 0 ], [ 0, 0, 0, 1, 1, 0 ], [ 0, 0, 0, 0, 0, 0 ], [ 0, 0, 0, 0, 0, 0 ], [ 0, 0, 0, 0, 0, 0 ] ] }
