Dear Tiago,

I am trying to draw float values associated with vertices in a graph as vertex texts. However, I get a peculiar output (file attached).  My code is given below:

import graph_tool.all as gt
import numpy as np

g = gt.collection.data['karate']

value = g.new_vertex_property('float')

for v in g.vertices():
    value[v] = np.random.choice([0.5, 0.8])

gt.graph_draw(g, vertex_text = value, output = 'test.pdf')
