涉及pygal，pygal.bar()。用geany和cmd視窗運行都是：cmd視窗正常，就是不顯示圖形
-------------------------------------------------------------------------
import pygal
from die import Die
# Create a D6.
die = Die()
# Make some rolls, and store results in a list.
results = []
for roll_num in range(1000):
result = die.roll()
results.append(result)
# Analyze the results.
frequencies = []
for value in range(1, die.num_sides+1):
frequency = results.count(value)
frequencies.append(frequency)
# Visualize the results.
hist = pygal.Bar()
hist.title = "Results of rolling one D6 1000 times."
hist.x_labels = ['1', '2', '3', '4', '5', '6']
hist.x_title = "Result"
hist.y_title = "Frequency of Result"
hist.add('D6', frequencies)
hist.render_to_file('die_visual.svg')
