Here is a minimal example:

The following is working:

import igraph as ig
import gravis as gv

lnames = ['0', '1']
edgelist = [('0', '1')]
graph = ig.Graph(len(lnames),  vertex_attrs={'name': lnames})
graph.add_edges(edgelist)
gv.vis(graph)

The following is not:

class mygraph(ig.Graph):
  def __init__(self, lnames, edgelist):
    super().__init__(len(lnames), vertex_attrs={'name': lnames})
    self.add_edges(edgelist)

graph = mygraph(lnames, edgelist)
gv.vis(graph)

This returns

ValueError: The provided data seems not to be in a valid graph format.

Is there a workaround?

Hi, when I use gravis to export html file.
It seem failed.
Could you help me. Thanks

I am trying to create a network graph with different edge length. However, the edge length is not changing.
My code:

G = nx.Graph()
for i in range(df.shape[0]):
    G.add_node(df.iloc[i,0], size=20, group='Compound', color='purple')
    G.add_node(df.iloc[i,1], size=14, group='Target', color='red')
    G.add_edge(df.iloc[i,0], df.iloc[i,1], weight=df.iloc[i,3])
figure = gv.d3(G, graph_height=1000, zoom_factor=1.5, show_details=False, show_details_toggle_button=False, show_menu = False, show_menu_toggle_button=True, node_hover_neighborhood=True, show_node_label=True, layout_algorithm_active=True)

I also tried using length instead of weight.

Any reason why this is happening?

Is it possible to include a option to get arrow_color == edge_color?
Thanks,

Hello,

Is it possible to have the label of a node be written inside of it ?

My graph roughly corresponds to a file system, i.e., the nodes of the graph are directories and files, and the edges correspond to the relation contains, e.g., dir1 -contains-> dir2, dir2 -contains-> file1.

The total number of nodes is too large to show them all at once. This is why I would like to start with some top nodes of the hierarchy and expand a given node on click (to show its neighbours).

Would that be possible with gv.d3(...)?

Is there any other "on click" response that is already implemented?

D3 has a set of symbols beyond the basic (circle, rectangle, hexagon). Is it possible to add a option to use these extra symbols?
Thanks,
Ely

If nodes/edges have associated time stamps, it would be great to have an animation of this over time, preferably with a slider and play/pause button.

Needs legends for links/node based on size/width or color/shape.

Is it possible to change the arrow style in directed graphs (something like adding an attribute for "arrowstyle", as is implemented in matplotlib https://matplotlib.org/stable/api/_as_gen/matplotlib.patches.ArrowStyle.html)?

Thanks,
Neta

panel
has a pane that displays HTML,
that unfortunately does not work with gravis.

Might this be an easy fix?
