graphviz2drawio's Issues

node shapes should be respected

Basic shapes should be supported (box, egg, hexagon, octagon, parallelogram). Conversion to rectangles is not ideal as shapes are usually basic vocabulary in many graph notations e.g. https://areyoumodeling.files.wordpress.com/2015/02/gsn.png

no fill in text attributes

This is alpha software, please report issues to:

Exception in MxGraph.add_mx_geo_with_points

graphviz2drawio/graphviz2drawio/mx/MxGraph.py

Lines 115 to 118 in 7519935

    
           for cb in curve.cbset: 
        
               ET.SubElement(array, MxConst.POINT, x=str(cb[0][0]), y=str(cb[0][1]))

               ET.SubElement(array, MxConst.POINT, x=str(cb[1][0]), y=str(cb[1][1]))

Line 117 here throws an exception when curve.cbset is empty, thus leaving cb unset.

use examples from https://graphviz.gitlab.io/gallery/ as test cases

Not sure how much help I can provide coding. But I can pull in a bunch of examples into a test directory.
The first one I tried caused segmentation fault so there's definitely fun to be had in there

Edge labeling

Is there a possibility to convert edge labels?

Reorganize packages

Goal: make it easier for new contributors to understand the architecture.

Things are somewhat messy now and the current 2 package structure is making less sense. Let's plan something better.

Error in parsing the graph for xml conversion with `fdp`

Hi Everyone,
I made the graph with pydot library using "fdp" layout parameter and also giving position for each nodes for the graph. While converting the graph to xml, it is giving error as :

Traceback (most recent call last):

  File ~\AppData\Local\anaconda\Lib\site-packages\IPython\core\interactiveshell.py:3505 in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)

    parser.feed(text)

  File <string>
ParseError: not well-formed (invalid token): line 64, column 109

Some relevant code info is as follows which I find was different than usual standard code:

# Create an empty PyDot graph
G_pydot = pydot.Dot(graph_type='digraph',layout="fdp")

pydot_node = pydot.Node(str(node), label=item['text'],shape=get_shape(item['shape_type']),slane=key,pos=f"{X},{Y}!") 

# Add the PyDot node to the PyDot graph
G_pydot.add_node(pydot_node)`

gdt=G_pydot.to_string()
xml = graphviz2drawio.convert(gdt)

multiple calls to convert fail

simple test:

from graphviz2drawio import graphviz2drawio as gv
for i in range(2):
    gv.convert("./test/directed/hello.gv.txt")

results in failure:

Error: syntax error in line 1 near '"'
Traceback (most recent call last):
  File "/home/jonah/.local/lib/python3.6/site-packages/pygraphviz/agraph.py", line 1201, in read
    self.handle = gv.agread(fh, None)
ValueError: agread: bad input data

Not sure why this causes a segfault in pytest but it looks like pygraphviz is not closing and reopening the file or otherwise properly resetting the read offset somewhere under the hood.

TypeError if charset is in handle of dot file

Error appears If charset is in dot file.
C-function agget (from line176 from agraph.py) returns bytes, but it must be string.
And C-func agattrdefval (from line 1833) returns bytes too.
And I think the same returning is of C-func agattrdefval from line 1741.

deterministic output

Given an input, the output should be the same every time. This improves testability. Currently at least node orders are variable.

Support invisible nodes

Hi, I'm getting KeyError on both invisible nodes in my graph. Seems that graphviz doesn't create those nodes when converting to SVG.

Here's the dot source and I'm adding the generated SVG by hand as an attachment as well. (dot -Gsplines=none anon.dot | neato -n -Gsplines=ortho -Tsvg -oanon.svg)

digraph G {
    graph [rankdir = LR, splines=ortho];

    node[shape=record];

    emmc [label="eMMC" color="blue"]
    boot_host [label="" style=invis width=0 height=2]
    spinor [label="SPI NOR" color="green"]
    soc [label="SoC" height=4]
    nand [label="Raw NAND" color="yellow"]
    dev_eth [label="" style=invis width=0 height=2]
    eeprom [label="I2C EEPROM" color="red"]

    emmc -> soc [arrowhead=none]
    boot_host -> soc [xlabel="Boot Source"]
    boot_host -> soc [xlabel="USB" dir=both]
    spinor -> soc [arrowhead=none]
    soc -> nand [arrowhead=none]
    soc -> dev_eth [xlabel="USB-OTG" dir=both]
    soc -> dev_eth [xlabel="Ethernet" dir=both]
    soc -> eeprom [arrowhead=none]
}

Fix edge layout

Edges / arrows are often layed out incorrectly, fix in 0.0.6

Error in convertion - from dot to drawio

I have a dot file that I want to converto to drawio.

fillcolor not refrected

Simple example fails with `IndexError`

Thanks for this tool... and very timely for me.

Your SmileyFace example is working fine, but simple graphs seem to fail. For example, the PyGraphics quick example:

import pygraphviz as pgv
G = pgv.AGraph()
G.add_node('a')
G.add_edge('b','c')

from graphviz2drawio import graphviz2drawio
graphviz2drawio.convert(G)

gives:

    nodes, edges = SVG.parse(svg_graph)
  File "/Users/zachary/miniconda3/envs/py36/lib/python3.6/site-packages/graphviz2drawio/models/SVG.py", line 20, in parse
    nodes[title] = node_factory.from_svg(g)
  File "/Users/zachary/miniconda3/envs/py36/lib/python3.6/site-packages/graphviz2drawio/models/NodeFactory.py", line 46, in from_svg
    rect = self.rect_from_svg_points(SVG.get_first(g, "polygon").attrib["points"])
  File "/Users/zachary/miniconda3/envs/py36/lib/python3.6/site-packages/graphviz2drawio/models/SVG.py", line 28, in get_first
    return g.findall("./{http://www.w3.org/2000/svg}" + tag)[0]
IndexError: list index out of range

thanks!

Support for compound=true

The DOT guide (https://www.graphviz.org/pdf/dotguide.pdf) gives an example of a "compound" digraph, which renders with edges between two clusters and edges between nodes and clusters:

digraph G {
  compound=true;
  subgraph cluster0 {
    a -> b;
    a -> c;
    b -> d;
    c -> d;
  }
  subgraph cluster1 {
    e -> g;
    e -> f;
  }
  b -> f [lhead=cluster1];
  d -> e;
  c -> g [ltail=cluster0,lhead=cluster1];
  c -> e [ltail=cluster0];
  d -> h;
}

When I convert this with graphviz2drawio, all the cluster information seems to get lost, and all the internal nodes are just connected together. Is there a way to get the conversion to keep the compound subgraph information? Or are you possibly planning on adding support for that?

The graphviz2drawio conversion:

Pip install pygraphviz fails on mac M1

The PIP command for installing pygraphviz on a macbook with the Arm M1 processor fails.

This command does work:

python3 -m pip  install  --global-option=build_ext \
  --global-option="-I/opt/homebrew/include"\
  --global-option="-L/opt/homebrew/lib"  pygraphviz

Python 3.4 circular imports

For whatever reason Python 3.4 can't handle the circular import SVG->NodeFactory->SVG

  File "/home/travis/virtualenv/python3.4.6/lib/python3.4/site-packages/graphviz2drawio/__main__.py", line 2, in <module>
    from .graphviz2drawio import convert
  File "/home/travis/virtualenv/python3.4.6/lib/python3.4/site-packages/graphviz2drawio/graphviz2drawio.py", line 4, in <module>
    from .models import SVG
  File "/home/travis/virtualenv/python3.4.6/lib/python3.4/site-packages/graphviz2drawio/models/SVG.py", line 3, in <module>
    from graphviz2drawio.mx.NodeFactory import NodeFactory
  File "/home/travis/virtualenv/python3.4.6/lib/python3.4/site-packages/graphviz2drawio/mx/NodeFactory.py", line 1, in <module>
    from graphviz2drawio.models import SVG
ImportError: cannot import name 'SVG'

Probably fixable by moving SVG.parse somewhere else and remove the imports of NodeFactory and Edge from SVG module.

Convert cubic bezier in SVG to curved edges in Mx

This is tricky because:

SVG paths are often comprised of multiple bezier curves
draw.io does not natively support bezier curves
@davidjgraph noticed your starring, thanks 😃Any thoughts?

conversion fails on .dot file created by graphviz with python with a `path` shape

I've created this file using graphviz in with python and it won't convert to .xml for drawio.
could only upload a compressed file. Dot not supported for upload here for some reasons.
