Options

Options	Description
--in_json	Treat input as json object
--in_coords	Assume that input contains coordinates
--in_file	Set the name of the input file
--skip_planar	Skip planarity checking & drawing
--transform	Choose transformation type (allowed intersections, springs)
--out_type	Set the output type (allowed normal, json, tikz)
--out_file	Set the name of the output file
--iterations	Set the number of iterations

Examples

build/./drawer --in_file examples/0.json --in_json --skip_planar --out_type normal --transform springs

Graph formats

Graphs on input are assumed to be connected, undirected and simple.

Input

• JSON object
  Positions array is optional. Nodes in edges array should be values from 0 to n-1.

{
    "size": n,
    "edges": [
        [0, 1],
        ...
    ],
    "positions": [
        [0.5, 12.0],
        ...
    ]
}

• normal
  If present (must be specified with --in_coords flag), the position list should have length n.

n m
0 1.2 3.0
...
n-1 12.0 1.2
x_1 y_1
...
x_m y_m

or, if flag is not not specified:

n m
x_1 y_1
...
x_m y_m
