To answer one of my issues..
I figured out how to get the buttons to delete more than one vertex in
your html example. I used this code...
'subgraph_vertices=vertices.difference
([to_delete,to_delete2,to_delete3,to_delete4])' and it seems to work
nicely. Does this seem like the best solution?
Still can't get the buttons to default to 'none'.
And I am using letters as my vertices. So my original info looks like
this...
fw=DiGraph({'A':{'I':'1.0'}, 'B':{'D':'1.0','E':'0.3','G':'0.4'}.....
But the button selectors are 0-10 and they don't correspond to my
letters so they don't do anything. How can I either...
1. make the buttons be letters and recognize my vertices. -or-
2. map the 0-10 to the letters A-J?
And is there a way to size the html table - it is way to wide to see
both graphs side by side effectively? I tried the html.table? but
there doesn't seem to be an argument for size. Either that or perhaps
if I can scale the graph down to a smaller size, the table will shrink
with it. But figsize='x' doesn't seem to work here. Or if I add it
as plot(blah blah blah).show(figsize=[5,5]) it removes the graphs from
the html table and thus they are no longer side by side. Any ideas?
